Re: cheap but good thermal paste?
I've seen the HY410, HY510, and a whole bunch of other HY**0 formulations. Have you tried just the HY410 from multiple containers, have they been consistent?
I've seen some reviews of some HY**0 were pretty good too, and there were some that weren't so good... The **0 number seemed to indicate better pastes (higher is better) but there were some that didn't come out so well though it could be consistency or fakes...
... fake CCP? Is that real?
I suppose it is possible... BTW I think the CCP I got, if it's not a fake, is "GD900" ... seems good enough, at least it survived the multithread java program that has been causing problems. There will be a few compile jobs that will be next on the test list but I can't recall which were the worst, probably webkit or webengine...
Only ended up with 2 grams of the stuff so it's not exactly super cheap compared to the ZnO, but hopefully this will still last a while.

Re: cheap but good thermal paste?
I've been using this cheap stuff in small buckets called "HY410" for years.
I got some at first back around 10 years ago when I was replacing thermal paste on a very large number of laptops and desktops both. I also use it when replacing voltage regulators.
All the machines i used it on still work great to this day, performance is good enough, sure you may get an extra degree or two at best if you use arctic silver 5 or something. but I even use this paste on my own PC's and PC's i build for others.Leave a comment:

Re: cheap but good thermal paste?
Here we go... a syringe of CCP...
Last night I was running a multithreadded java program. Dozed off and forgot about it but came back and noticed my computer was screaming at me as it was overheating! Was hitting well in excess of 90°C where I set it to beep if it gets that hot. It probably hit 95°CFortunately it does auto-downclocks when it hits that high. I manually downclocked it 10% let it finish and stay below 90°C.
So now with this gray CCP... Quite a bit thinner than the ZnO I had, but about same consistency when I mixed in some silicone grease. So that old ZnO probably needed some more grease mixed in to get thinner consistency so it can spread easier.
Now I try the same java program... so far so good, hit 86°C for a while but tends to hover around 84°C with all cores blasting. This is probably almost 10°C cooler and no longer triggers last resort thermal throttling.
I'm surprised...<- not quite the right smiley but the smiley code for this fits the description. Worth the $1.30.
One thing new I noticed: the heatsink actually got warm/hot. This is the first time I've ever felt a heatsink get this warm - this is actually a good sign that heat is being conducted away from the CPU. I think the ZnO might have to be relinquished to just older devices, or the round file ...Last edited by eccerr0r; 08-10-2021, 04:24 PM.Leave a comment:

Re: cheap but good thermal paste?
Well bought a small 2g sample of CCP... we'll see when it shows up... (in a month...)
Seems my p4 works ok with ZnO but my Core2 and i7 seems to get quite hot.
I alsp have this "Hutixi" thermal paste sample, not sure what this CCP is like...Leave a comment:

Re: cheap but good thermal paste?
I've seen some reviews of CCP (no not chinese communist party but cheap chinese paste) and some turn out better than thought. Also cross referencing some of them to other reviews using baselines, the CCPs actually seem very good...
But a good point is made about CCPs - don't know how variable they are and whether I'm getting the good stuff or not...Leave a comment:

Re: cheap but good thermal paste?
The difference between known non conductive metal compounds is a couple of degrees at idle but can be as much as 12c difference at load. https://www.pcgamer.com/geek-tested-...es-face-off/2/
How 20 year old paste and $2 paste compare against them and each other who knows.Leave a comment:

Re: cheap but good thermal paste?
Well, if this was was a professional job, things would be different... Plus 2 decades ago, heat sink compound wasn't as widely varied as it is today, pretty much all the heatsinks and TO-220 is ZnO...
Anyway I added a little extra silicone grease to make it spread much easier, so not too bad on that front. But what would be a good tradeoff on paste, will that HY510 (which is an acceptable price...) exceed that of the ZnO that I do have, or will there be a better option somewhere?Leave a comment:

Re: cheap but good thermal paste?
A quality made paste with known spec will do a known job. It's why all the pros I know use decent stuff. Yes a little different when money is involved but even the expensive paste is cheap.Leave a comment:

Re: cheap but good thermal paste?
That's what I'm fearing, I just reapplied fresh ZnO paste on my cpu and it's still quite hot, wonder if changing pastes is worth the money or am I just tossing money down the sink...Leave a comment:

Re: cheap but good thermal paste?
1. The price (obvious);
2.1 Silver based thermal paste => higher rate of electrical conductivity and capacitive value;
2.2 Liquid-metal based thermal paste => highly corrosive;
Overall the most challenging is knowing what you're buying since its composition is often missing, and rating by color is like dishwasher detergents
A good ZnO based thermal paste, or even better, a good AlN based thermal paste, will achieve basically the same results if correctly applied and renewed every 1 to 2 years.Leave a comment:

Re: cheap but good thermal paste?
ZnO is a ceramic. And I figure I paid a pretty penny for Made in the USA then (though I think I probably paid $6-8 or so, but again I don't have any recollection).
HY510 = ? Is it better than ZnO? At this point I need something "better" than ZnO unless it's simply due to the fact it's 20 years old (though I doubt it...)
I'm just hoping for a 10°C drop in temperatures over ZnO... is it even possible? I just hate the fact people just rate by color... and not tell what the material is, even generalizing what kind of material (what ceramic?)Leave a comment:

Re: cheap but good thermal paste?
It seems I was talking arse on it being more expensive 20 years on. It's even got specs on the side, how accurate they are..?.. https://www.aliexpress.com/item/32965194236.htmlLeave a comment:

Re: cheap but good thermal paste?
MX2 (ceramic) is cheap.
MX4 (carbon) is a bit more if you need extreme performance.Leave a comment:

Re: cheap but good thermal paste?
Anything is obviously going to be more expensive 20 years later. The lack of any details from them and the scarcity of it currently suggests there's nothing special about it and anything would do the job.Leave a comment:

Re: cheap but good thermal paste?
https://www.rawnamerica.com/whats_new/heatsink_pr.php ... don't remember how much I paid for it, probably on the order of 20 years ago. 1 oz (28g), pretty sure I paid less than $10 for it, "lifetime supply" I was thinking then.
I still have around 10g left in the tube and the tube has decayed over the years which is somewhat problematic as it's now leaking. However I have to say : I'd be "disappointed" if I don't get 10°C (my absolute minimum would be 6°C else I'd be very angry) difference from a "better" thermal compound than this stuff, especially if I'm paying many times the cost...Last edited by eccerr0r; 07-10-2021, 06:40 PM.Leave a comment:

cheap but good thermal paste?
What's the cheapest thermal paste people get that's consistently "decent" ... I'm wondering if I should switch from zinc oxide to something else, but don't want to be disappointed.
Again needs to be cheap... ideally something as cheap as zinc oxide but I figure if it's claimed "better" then it means "more expensive"... which would add to the disappointment.Tags: None

by Veyron7887Hi. I have Asus X55C laptop from year 2013. It has i3-2328M CPU. I replaced stock thermal paste with high quality thermal paste. Before thermal paste replacement, I measured CPU temperature Around 65-70 degrees Celcius with stock thermal paste. If after the replace thermal paste, I measured CPU temperature around 80-84 degrees Celcius and fan don't stop when system is idle. I replaced the thermal paste several times but still did not change. Where is the problem?

by MgiffuneI have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -

by the_remHello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow... - Loading...
