Temperature / Cooling Issues

[Ignitionnet]

Hi All,

Had a system delivered 3 weeks ago, for the past 2 weeks my fan controller, NZXT Sentry 2, has intermittently complained of losing contact with fan 3.

Ran some tests and seeing high temperatures on both GPUs - GPU cores can be taken up to 95C in 5 minutes of loading, with PCI-E slots going over 70C.

All fans on the machine seem to be spinning happily, however the system is getting dangerously hot despite still running on stock clocking.

I'll repeat there is absolutely no overclocking going on here.

The cards are 2 x GTX 570.

Anyone have any thoughts on what I can try here? I really don't want to have to RMA the system within 3 weeks of receiving it but there's clearly a pretty major issue here.

hi, i totally understand how ya feel..

i notice ya got a pretty high end rig inside of a small mid tower case.

do you have a side fan fitted? (the big fan on the side of case) I'm assuming not as the titan is massive and probably prevents the fitting of the side fan.

What temps are you getting at idle? i know that two cards run hotter than one card.

As tom said above you have a lot of components in a smaller case really you could have done with a Haf 922 at a minimun to get better airflow, having 2 GPU's from all the tests i have seen add between 10C-20C on the top card so when doing anything intensive you may find the top card in the 90's so with all what you have in that case i think you can very well expect the lower card to be increased in temp aswell, what are you using to run your tests as you have not said (game or other program? ) if you are running one of the benchmarking programs they are going to push your cards to the limit's hence really hot temps also seen as you have a fan controller have you tried putting all the fans on max when you are doing anything intensive?

YOu could maybe get a spot fan, such as the picture below. Direct it at the hottest part of your rig (top gpu i presume)

Going to get an additional case fan or two, I've mitigated this for now by placing a floor standing fan just outside the case, temperatures no longer go critical.

Getting Nowhere Fast

Just to update this thread... after some back and forth with tech support I'm no closer to solving it.

I would welcome you guys' thoughts on this - I've stated the problem to support 2 or 3 times and we don't appear to be getting nowhere, they want to explore moving motherboard sensors around - unsure what this will accomplish when the GPUs are nearing critical temperature.

Case Open
Case Closed Up
Temperatures With Floor Fan
Temperatures Without

I could've gotten the temperatures higher on the without picture but I bottled it as GPU 1 was nearing critical temperatures.

Please any advice welcome, this is outside of my experience and although I opened the case at the same time as I opened this thread I've gotten nowhere with tech support.

As Tom and Fear said in posts 2 and 3, there's a lot of stuff in that case. The PSU and two gpu's are really close together and will be giving off a lot of heat.

Running Furmark will make the temps go really high (especially with the two cards and PSU situation). What temps do you get when just gaming rather than running Furmark?

You could try running just one card (furthest one from PSU) at a time and see what temps you are getting then. If it's much better, then you'll know it's the fact that there's too much 'hot stuff' running close together and may need to cosider a bigger case if you're not happy how it stands.

My gpu has always run hot at around 68c when gaming and will hit 95c on Furmark (IIRC).

Anyway, try some of the above if you fancy it and let us know the results.

To be honest, I think ya high temps are preobably because you have a really high end rig inside a small case. I'd upgrade ya case, sorry to be blunt, but that's what i think the problem is. What do the experts at pcs say?

oh don't run furmark its really bad for gpu's. try "3d mark something" cant remember the full name.
