Hi guys, So i have a vaporX 5870. Runs really well and seems to have no issues but with BF3 and Skyrim. now i think the reason is that only those 2 games push the card. So after playing either for around say 20 min the temps on the card go way up.

ADA64:
GPU Diode (dispIO) will show around 58c
GPU Diode (MemIO) will show around 64c
GPU Diode (Shader) will show around 68c
this is with the card fan at 75%

Now i know these temps arnt bad at least i dont think so but if it gets any higher i think around 70 the card shuts down and display is killed and the card will have fans go to max. im assuming its the safety procedure for high temps hitting the peak. My MCP, north bridge on this MB was causing issues before ( Zotec 9300) but i fixed that and now its only maxing at like 52c.

So Either the card is not cooling itself corectly or my case cooling is not good enough or something in between??

System specs
Water cooled CORSAIR CWCH50
Pentium 6300 O.C to 3.4Ghz
Zotac 9300 G-E
4G Ram
Sapphire Vapor x 5870


Also is there a way to check after the fact of the card/computer crashing? is there logs somewhere?

I think you've got more problems then just the temperature, the card shouldnt be shutting down at 70c. That's warm, but far from excessive, the 5870 has a max of around 105c so you're a good way off.

What case have you got, just out of interest?

I have a Cooler Master CM 690 II. Now at this time i have a front 120mm fan, side 120mm fan and a top 120mm fan. system stays quite cool unless gaming. but most games run fine and cool just bf3 and skyrim my luck lol

Based purely on the temps you have said it doesn't appear to be a cooling problem, those temps aren't excessive at all and as adam has said they are well within thermal specs for the card.

Exactly what make, model and wattage is your power supply?
What direction do the installed case fans blow (in or out), although I don't suspect a problem here again based on your temps.

PSU does seem to be a likely suspect, both skyrim and BF3 are quite heavy on resources so if your power supply is only just enough that would be a good reason for it cutting out.

If it is high enough wattage + decent brand, might still be worth having a look at your voltages.

Well on specs alone that PSU is just about good enough, cant say I've ever heard of the manufacturer Nexus so am unable to comment on their build quality.

To be sure it's not the problem you're going to have to find a known good replacement PSU, it's a pain but neccessary to rule it out.

That card is not very hot at all. What is the video card RAM?, although I cant believe that is the problem...try the PSU replacement...that just doesn't seem right that the PSU is not good enough...

Yea and i really think replacing the PS is kinda an expensive test.I dont have one laying around. i would hope to find another way to figure the issue out, i would think that the system failure would have some sort of crash log somewhere showing the reason.

How old is your PSU, I have been trying to get some reviews and more detailed specs on it but everything I can find is about two years old!

For a modern gaming system 540w is on the low side, with age, load and wear and tear that output will reduce. PSU problems can manifest themselves in many wierd and wonderful ways, so never discount it.

Try downloading and installing HWMonitor, as long as your board etc has the relevant sensors this can give you an idea of your PSU's output. It is better to physically test it with a PSU tester or digital voltmeter, but software is free and a good initial test.

When installed, run the program and either post all the displayed min, max and current voltages for your PSU or just screenshot it and post that. Then, with HWMonitor still running in the background, run a game for 5-10 minutes (hopefully without a problem) then post the HWMonitor results again. The software isn't perfect and does, occasionally, report really out of range numbers. This is normally due to incorrect interpretation of the sensors outputs, anything that looks really badly out is worth double checking in the BIOS which will be accurate, just harder to load test.
