Furmark and prime, same time, burning smell.

Re: Furmark and prime, same time, burning smell.

120mm fan o psu (off when idle)

120mm fan o cpu (low speed when idle, about 1000rpm)

120mm fan in front of the 4 hdds (antec tricool, lowest setting)

140mm fan on top case (lowest speed, about 7-800 rpm when idle, sometimes up it to medium (1200rpm) or high (2400 rpm) when doing video encodings.

passively cooled video card

no problems for the q6600 and no problems to sleep at night. The number of fans is not relevant, the airflow is and the components you use is.

My system is on the more expensive side though, with the Seasonic X-650 gold efficiency doing up to 92%, the video card with Accelero S1 Rev 2 doing a hell of a job spreading the heat .. etc

Erh. I always thought the more fans, the more airflow

Re: Furmark and prime, same time, burning smell.

My PC has a single 140mm intake fan, 2 92mm CPU fans (push pull). The only exhaust fan is the bottom mounted PSU fan, and it never hits much more than 50*C under load

Most of the PCs (Core i3) I build have the stock intel cooler and a single 92mm exhaust fan. They idle at around 30*C, and hit maybe 40 under load.

Re: Furmark and prime, same time, burning smell.

You are talking about 73 watts top here plus you have intake fan and the rest goes through some grills I guess thanks to natural convection.

Can you see the difference between this and 89, maybe even 125W Athlon 64 X2 6000+ together with 165W HD 3870? That is 300W worst-case scenario. With just crappy PSU with low efficiency pulling all that heat through itself, also remember the hotter it runs, the worse the efficiency is. I sometimes wonder how the crap PSU's can sustain that for all those years. But when everything inside has 50-60 °C, people are just shortnening their components lifespan. Remember RoHS and stuff.

Before making any more recomemndations, I want to see his internals. May have stock HD 3870 blowing air from case, just dirty and with degraded thermal compound. And no intake fan. May as well have some custom design like Sapphire's, keeping all the heat inside the case.

Re: Furmark and prime, same time, burning smell.

I am so sorry, started this thread when drunk and completely forgot about it.

Anyway, I was playing dead island yesterday and got the same smell.

My pc went pop and turned off, the psu gave up on me. , took some pics for you to look at. Sorry they are 2/3 months late.

The psu looks crap inside, I now have a 300w psu in my pc and its fine, no funny smells when playing dead island.

Also included pic of inside pc, The front intake is on a switch, i only use it when playing a game.

Please dont shoot me.

I must add that I had also just put a little OC on it, only to 3.2ghz.

Re: Furmark and prime, same time, burning smell.

It's a Sun Pro. No wonder it died. I REALLY would have replaced it before it failed, as it could have killed your PC. I've killed several Sun Pros on my load tester before. They usually go kaboom at around 300W.

Re: Furmark and prime, same time, burning smell.

Are you sure they are SunPro? Just to be sure.

Here these PSUs with almost the same label have been made as Eurocase (Partis is the company selling it here). I have one similar and to be honest, it is really much beefier, also has 14cm fan. I have also beefed the capacitance everywhere by great margin. Using it as spare/testing PSU, over years it handled up to aproximatelly 400 W load.

The thing is, this Partis company seems to be recycling it's PSU series every several years. So as long as this model has been tough to get in last 2 years, it is poping again on market. Want to get them on ym bench too

Re: Furmark and prime, same time, burning smell.

The only other I had lying around that I had to put in my pc is a fsp group 300w FSP300-60THA

Re: Furmark and prime, same time, burning smell.

Quite good PSU, but I would recap it for long-run.

Yes. Definitely Sun Pro. TB-______ markings on the 2nd line of the transformer are a giveaway.

Please use dremel or wire cutting pliers to ged rid of those disastrous fan-strangling grills , the one behind the exhaust case fan at the least.

Re: Furmark and prime, same time, burning smell.

Sun Pro has worse, that's for sure. Tiny diodes though...

Re: Furmark and prime, same time, burning smell.

At 240V, those diodes are good enough for a power supply that blows up at 300W.

I see that the it is "sacket" 775 ready.

Furmark =/= Futuremark.

Carry on.

Glad I'm the only one that noticed that

Never noticed that one until now.

I tested a PSU from CoodMax (no, I didn't mean Coolmax) recently. It's label said not to ermove the cover

I noticed that too, but i never write in joined up writing so just thought that was normal ha ha. Well spotted.

No dremel or tin cutter

I will hack it to death, will never be seen anyway.

Re: Furmark and prime, same time, burning smell.

It's worth the trouble.

How do different fan mesh patterns affect fan and chassis airflow?
