Re: Forcing a video card fan to always run at full speed.
Silicone grease. Take a little bit from the can using a toothpick. Use a hot air station, hair drier, or a lighter or small blowtorch from a distance to melt it into liquid and let it flow inside the fan bearing. Goes back to paste once it cools down below 60C, thus it does not flow back out.
If the bearing has been thoroughly cleaned beforehand and is not damaged, it will keep going for 1 year or more.
Sadly nowadays more low-quality fans come with sealed bearings - that sucks. I have tried drilling a hole and putting lube in that way but it inevitably makes metal dust that falls inside and makes scratching noises.
Speaking of secret stuff however, i do wonder what kind of lube Matsushita/Panasonic put in their fans - the likes of old laptops like HP Compaq business models and some Toshibas and Sony Vaios had Panasonic fans. They have sealed bearings but i've never seen one seized or grinding, even in laptops that had never been cleaned in their 8- or 10-year lifetimes. That kind of lifetime is unmatched by any other manufacturer afaik.

Re: Forcing a video card fan to always run at full speed.
one method i use to force a 4pin pwm video card fan to run at full speed is to hotwire the fan connector. or rather i use a needle to remove the blue wire pin from the fan plug connector. this removes the pwm pulse sense pin and makes the fan run at full blast.
however, some multiple fan video cards dont have this pwm pin or some only use three or two pins for the fan. in which case, soldering a jumper wire like stj said is the only way.
for some cards, the fan profile curve is controlled by the video bios. in which case, modding and reflashing the video bios is the "soft" solution instead of resorting to hard mods on the card. rather than cross-flash using the video bios of another brand's card, u might as well just mod the existing video bios. modding the existing bios has less chance of bricking the card than trying to cross-flash.Leave a comment:

this is dragging on, just put big fans on it hooked to the psu - mad-max pc!

Re: Forcing a video card fan to always run at full speed.
We saw no switch and I did take it apart enough to get the circuit board, so I don't think this has dual BIOSes. I've seen dual BIOSes for motherboards, but never for video cards. I generally go for the nVidia type of video cards personally. Do the newer nVidia cards do the dual BIOS for the video cards as well or is this mainly an AMD video card thing?
Thanks Per Hansson!Leave a comment:

Re: Forcing a video card fan to always run at full speed.
Ah sorry I missed that
EDIT: Btw it's pretty common with a dual BIOS design on AMD's graphics cards, but guess your's don't have it?
(There should be a switch on the card to select which chip is active if it does).Last edited by Per Hansson; 07-30-2017, 04:02 PM.Leave a comment:

Re: Forcing a video card fan to always run at full speed.
It's not that important what oil you use (just DO NOT use grease). Car engine oil is fine. What is VERY important is how you oil the fan. Most people just pop the rubber cap and put a drop of oil, but that is very ineffective and lazy method.
To oil a fan properly, you have to take it fully apart - that is, separate the rotor (fan blade assembly) from the stator (the fan case). Typically, most cheap sleeve bearings just have a plastic "C" clip/washer on the shaft to hold the fan blade assembly in place. You just remove that, and the fan can be taken apart.
The most important part is cleaning the sleeve bearing. I take a drill bit that is a few sizes smaller than the fan shaft and rub the drill bit back and forth in the sleeve bearing opening. Then force tiny IPA-soaked paper towel balls through the sleeve to clean all of the grime inside.
Using a drill bit or something slightly abrasive to clean the bearing is key. This cleans the build up of shaft/bearing material debris, which in many cases is what causes a fan to seize. It also creates microscopic grooves parallel to the shaft of the fan (and perpendicular to the turning motion of the shaft when the fan is spinning). So when you put oil in the sleeve bearing, it fills in those micro-grooves and essentially they act like tiny oil reservoirs, keeping the bearing lubricated for much longer. The concept is somewhat similar to how a rifle bearing works.
Doing this will make even the cheapest sleeve bearing fans last many years.
Ah, makes sense now. I've seen some fancy cables like that at my previous job - some red/black cloth-covered cables. They looked neat indeed. But I still prefer my high-power cables to be soldered and not modular. The connectors add too much resistance and are just another failure point.
On the other hand, modular PSUs at least allow me to get rid of SATA power cables and only keep my Molex.

Re: Forcing a video card fan to always run at full speed.
What oil do you use for the fans? Maybe the ones I've tried had the bearings that you said you couldn't do it with, but at best, I get maybe 3 extra months out of the fan before it seizes again from all the dust. I've tried it a few times on laptop fans. I researched for better oil, but I guess the stuff the manufacturers use is a bit of a secret.
I think the modular cables for the 4-pin and 24-pin would be for those people that have show cases. Sometimes, they like to change their wires around a bit or get shorter or longer ones (which can help with hiding the wires, etc).
I've seen a case where the guy had some wires that had some sort of metallic looking shield around each wire. Where it connected to the PSU, it screwed in. It looked kinda nice.Leave a comment:

Re: Forcing a video card fan to always run at full speed.
I thought I did say what card it was. The PowerColor R9 380. I had found firmware for the MSI that had different timings, despite them being the same model card. I saw people were changing the timings on these cards using the firmware editor. He's a gamer, so maybe that might be something worth trying in the future, now that we got it running stable.Leave a comment:

Re: Forcing a video card fan to always run at full speed.
The Irony is that the company now seems to use kinda decent fans...
And it was a Corsair Guy in a German Forum (I believe it was Hardwareluxx) who said that they don't need high quality fans because of semi fanless.
And that's the issue. High Quality fans are expansive as shit. With 2 fans expect to pay something around 20-50€ more for good fans...
That's why nobody does use really good fans. They are just THAT expansive.
And don't forget the lubricant. You want to use a very high quality lubricant and not just enough for a year or two...
You open up Radeon Settings, click on games. Than Global Settings. Global Wattman (or Overdrive, depending on Card) And there you have somewhere something to adjust the fan speed.
You adjust them to wherever you want, hit apply and it is applied. No need for external software at all

Re: Forcing a video card fan to always run at full speed.
What i meant to say in that post was that if you have a video card that never runs its fans due to design (not fault with the fans), then clearly it is easiest to do something about the fans on the software-level - i.e. force them on at a certain speed in idle and maybe several different speeds ah higher loads, depending on temperature.
In regards to oiling a fan: you can actually make a fan last longer than it did from the factory - even the very crappy fans. The fan(s) just have to cleaned and oiled properly. And this only works for sleeve bearing fans, which seem to have been phased out lately. All I see now is either decent quality ball bearing fans or crappy FDBs (fluid-dynamic bearings), which are essentially sealed sleeve bearings that are impossible to service unless you cut them in pieces with a dremel tool or a drill. I've actually done that, and have managed to save quite a few of those fans. Unfortunately, I still can't get them fully opened, so they cannot be made to last as long as a properly oiled regular sleeve bearing.
Good.
I hate stuff built on Net Lamework. Always seem to be sluggish. And I hate it even more when I am trying to use the same software in Windows XP, as XP does not natively come with .NET... and .NET tends to install some stupid start-up processes, making my PCs slower unless I disable them (which I always do).
Add modular cables to that list too. As if a fully modular PSU is better than a semi-modular one. But my question is, why the hell would you want your motherboard's 24-pin and 4-pin CPU cables to be modular? Isn't this what every standard ATX/mATX motherboard use nowadays anyways? -Some of these stupid trends need to die off already.
At least with the semi-fanless designs, the heatsinks and the PCs themselves tend to clog less with dust. So I will give them that much.Last edited by momaka; 07-28-2017, 12:31 PM.Leave a comment:

Re: Forcing a video card fan to always run at full speed.
Well you have not said what card it is exactly.
But if my guess is correct: https://www.msi.com/Graphics-card/R9...#hero-overview
Then why not use the utilities that MSI provides for it?
MSI Live Update 6
• Online update BIOS/Driver/Firmware/Utility. • Live Monitor auto-detects and suggests the latest BIOS/Driver/Utilities information.MSI Afterburner
...Additionally, the software's automatic fan speed control has received a lot of praise from enthusiasts all over the world. With MSI's "Afterburner", the decision to run the fan quietly or for high-performance is in your hands!Leave a comment:

Re: Forcing a video card fan to always run at full speed.
If that's the reason they don't use decent fans, that explains a lot (the semi-fanless statement). The fans weren't failing though and that was part of the reason for asking how to run them at full strength, for testing purposes. Was it something physically wrong with the video card? Was it something physically wrong with the PC? These were questions that we needed answered. As it turned out, it was something with the drivers and / or a combination of the drivers and the programs he had installed to control fan speeds.
A fresh install of Windows 10 didn't fix the issue, but we originally tried the same official AMD drivers he installed, which errored out during installation. I believe they just mistook the error out message for a Your drivers were successfully installed message.
Installing the other driver from AMD's website (a little older) fixed the issue. As soon as we got the successful installation, we saw the fans kicking on when the temp reached a certain point.
He will more than likely be needing newer fans sooner or later though, if he keeps running it the way he's been running it. Side completely off and a big box fan blowing air into the side of the case. When I originally got it and we replaced his liquid cooling unit, we replaced the radiator (it was a closed loop system) and it was nice and clean. The other day when he was here, I looked in there and it was completely covered with dust! A full layer and I said we needed to blow that off and something was wrong. That's when he told me about the box fan and his place not being the cleanest. I told him he really wanted to keep the inside clean if he could. Nothing kills fans quicker than that dust!Leave a comment:

Re: Forcing a video card fan to always run at full speed.
Yes but they don't do it as bad as it is possible for Afterburner.
That digs very deep into the system and can cause problems with games and other software...
Things like clockrates are totally messed up. Like doesn't clock down in Windows or doesn't raise the clock for games.
True but the question is if the fan controller of the card is OK or if the fans are failing...
My guess would be that the fans are failing.
In best case a bit of oil for this kind of application may help (at least for a while)...
Or just replace the fan with other ones...
They don't use that no more and got rid of it again. Now they use Qt...
Well the others use (more or less) the same control panel they did around 20 years ago
Yes, and also that they don't need to use decent fans because of that shit.
The sad thing is that the uninformed populus believes that semi fanless might be an advantage...Leave a comment:

Re: Forcing a video card fan to always run at full speed.
Okay Per Hansson. Do these video cards use the BIOS chips that computers generally use? Those 24 or 25 SPI / I2C chips? If so, I got a reader / writer in case the BIOS flash does go horribly wrong. We won't upgrade the BIOS though. But we'll still need to flash if we change anything in that BIOS.
I was thinking of downloading both the current BIOS and the new one, and then dumping the current one and comparing them. That'd verify the current one and the one I downloaded are in fact the same. Then I might use that Tonga editor to figure out what's different about the new version. You know, try to figure out what they changed.Leave a comment:

Re: Forcing a video card fan to always run at full speed.
Just a suggestion: don't "upgrade" to a newer BIOS unless the manufacturer tells you it is ok.
Too big risk to brick the card.
If you want to make some changes to the BIOS then just use the one you have now.
GPU-Z can be used to dump the BIOS from your card:

It can then optionally be uploaded to their database:

Re: Forcing a video card fan to always run at full speed.
I agree with everything you said there. I'm thinking of using that Tonga video editor to change the target temp, because I feel that 78C is just too high.
I see the MSI R9 380 has some tighter timings at the higher speeds:
1425 MHz and higher is where the changes start. I see people have been changing the timings for the PowerColor using that editor to get more hashes for bitcoin mining (they're older posts), but now that his video card is fixed, I wonder if some mods like that would be a good idea. There's usually more to RAM than just changing the timing though. A lot of times, when you change the timing, you need to adjust the voltage. I'm betting the PowerColor uses different voltages for the Hynix than the MSI card uses, so maybe changing the timing isn't a great idea.Code:# PowerColor R9 380 Memory Timings: # CCC Overdrive Limits GPU Clock: 1200 MHz Memory Clock: 1750 MHz GPU Clocks 300 MHz, 483 MHz, 755 MHz, 839 MHz 880 MHz, 913 MHz, 948 MHz, 980 MHz Memory Clocks 150 MHz, 300 MHz, 700 MHz, 1475 MHz Memory Support 4096 MB, GDDR5, Autodetect 4096 MB, GDDR5, Elpida EDW4032BABG 4096 MB, GDDR5, Hynix H5GC4H24AJR Memory Timings (Elpida) tRCDW-tRCDWA-tRCDR-tRCDRA-tRC-tCL-tRFC 200 MHz: 0-3-2-3-7-6-12 400 MHz: 0-3-5-5-15-7-25 800 MHz: 5-5-11-11-31-11-51 1500 MHz: 17-17-22-22-60-19-97 1625 MHz: 19-19-24-24-65-20-105 1750 MHz: 21-21-26-26-70-21-113 Memory Timings (Hynix) tRCDW-tRCDWA-tRCDR-tRCDRA-tRC-tCL-tRFC 400 MHz: 4-4-5-5-18-7-39 800 MHz: 7-7-11-11-34-10-79 1500 MHz: 14-14-20-20-61-18-148 1625 MHz: 16-16-23-23-68-18-164 1750 MHz: 17-17-24-24-72-19-173 # MSI R9 380 Memory Timings: # CCC Overdrive Limits GPU Clock: 1200 MHz Memory Clock: 1750 MHz GPU Clocks 300 MHz, 473 MHz, 752 MHz, 837 MHz 879 MHz, 912 MHz, 947 MHz, 980 MHz Memory Clocks 150 MHz, 300 MHz, 700 MHz, 1425 MHz Memory Support 4096 MB, GDDR5, Autodetect 4096 MB, GDDR5, Hynix H5GC4H24AJR Memory Timings (Hynix) tRCDW-tRCDWA-tRCDR-tRCDRA-tRC-tCL-tRFC 400 MHz: 4-4-5-5-18-7-39 800 MHz: 7-7-11-11-34-10-79 1425 MHz: 14-14-20-20-59-17-141 1500 MHz: 14-14-20-20-61-18-148 1750 MHz: 17-17-24-24-72-19-173
Changing the target temp to something a bit lower though to get the fan to kick on sooner might not be a bad idea though and that's something we might do....
Originally, he had some guy redo the PC. They also downloaded the highest driver version from AMDs website. I don't think the guy actually read the message that pops up after it's done installing. The newest version (which I believe is a Beta version) says there was an error installing the drivers. It'd be easy to miss. One could easily mistake it for your drivers are properly installed, if they didn't actually read the message, like we did. With those drivers, the fans never seemed to kick on.
It wasn't until we downloaded the a-little-bit-older drivers that properly installed, where we able to get the fans to kick on when they were supposed to. This makes me think that was the issue. For some reason, whatever wasn't properly installed with the first drivers was somehow in control of turning the fans on / off. What was odd, while the drivers were installing, when the screen flashed, the fans would kick on. It wasn't until that message appeared at the end that they'd stop and not turn back on.
With the other drivers, same screen pops up, but instead of saying there was an error, it says your display drivers are properly installed. Both messages require a restart.
The generic Microsoft drivers are the ones that were alternating the fans. One turns on for maybe 5 seconds, the other one turns on, the first one turns right off, and then it repeats.Leave a comment:

Re: Forcing a video card fan to always run at full speed.
That's normal for many new video cards. They don't run their fans fully until they reach a certain temperature (which usually is too high, IMO).
Yup.
Well that applies for any program that can control the fans. The key is to not play with settings that you don't know what they do.
If you have a video card that never turns on its fans until it burns you, that's a guaranteed failure. In that case, might as well "try stuff" with MSI Afterburner or other software and get it exchanged when it burns... because it would do that anyways with a stupid fan curve.
Ever since AMD started using .NET for their Control Center (which was a super long time ago), I've been avoiding it whenever possible (typically, I just installed the drivers without ATI CC). CC is not very good for low-level stuff. Even fan control is wonky compared to what other programs out there offer.
Yes, I'm not a big fan on semi-fanless either. Seems like just another excuse for the industry to have more hardware fail (i.e. planned obsolescence).Leave a comment:
