PC Overheating Issues, need help.

[Zobbar]

Hello,
I recently upgraded to Crossfire and its been great ( I can now do 4k). There is one major problem... My 2nd (Bottom one) is a 7870tahit and it gets real hot, it runs at ~90C and once it reaches around 92C it makes my PC crash and the screen gets black with random dirty white lines near the top and then shuts off, during this process the headphones make a terrible noise sounding like baaaaaa electronically. The 1st gpu 7950, is at a good temp. (77-85c) and does not make issues. Note all fans are on max rpm. What can I do to fix it?

 

[Zobbar]

RMA the cards if they are under warranty. 100% fan speed should cool the cards easily. Most GPUs don't get over 50% fan speed at the hottest.

That will cost me $40 for both of them because of XFX shipping D:.

Well, its that or nothing it looks like. If the fans really are at 100%, the cards are messed up and need replacing.

Can it just be the software's fault... just 3 days ago the temps were 77c for the 7950 and ~83c for the 7870 tahiti.
How does it jump so high. There was a difference in temp for the room but not that high!

 

[tiny voices]

No, it is not a software issue.

What is the room temp difference? Also, did the cards overheat in your Bitfenix case?

Only 1 card was in there and as far as I remember temp was a bit (2-3c) better... 5c at most, let me check.

That case is WAY better than the one you have now.

 

[Zobbar]

Yes little bit less than 5C difference outside, in home it should be less. It's just wired that the temps. for both gpus spiked up so much... Just earlier today the 7870xt was at 92 and the 7950 was at 83.

 

[Zobbar]

That case is WAY better than the one you have now.

Really, I could not notice it... its smaller. And I just sold the Bit fenix one... for cheap

Yes, the bitfenix case was WAY better quality and design. You made a mistake changing it for this other case.

This one looks like its better, so I deceided to switch! Should I get the bit fenix one back?

 

[tiny voices]

I would. It has a bottom mounted PSU, which is a WAY better and newer design.

Anything else other than better power supply placement, Lower temps?

 

[Zobbar]

Just something to add... 3 days ago, weather outside was 5c less, so less in the room, and the cards were 7870xt 83c and 7950 77c. 6 hours ago temps were 7870xt 92c and 7950 84c.

This is a dramatic change that I cannot explain! Any help?

Better design, newer, more cable management.

Look at that clean SLI build in the Merc Alpha.

Will the temps be lower? Looks are less important to me... Also the Extreme engine has a back panel which you can open and the merc does not.

 

[Zobbar]

Look here

I was not saying the build looks better, I was saying it is clean and neater so it will have better airflow than your mess of cables in your current case.

I don't really know what else to tell you besides RMA your cards.

That's not a very viable option and it's a last resort...
I just can't understand why this is:
3 days ago, weather outside was 5c less, so less in the room, and the cards were 7870xt 83c and 7950 77c. 6 hours ago temps were 7870xt 92c and 7950 84c.

This is a dramatic change that I cannot explain! Can you answer it?

Thank you for being so helpful you are so kind 😀
