Something is wrong, one Xfire card hits 2x the temp under load...

post #1 of 20
Thread Starter 
When running intensive programs my top cpu hits 95c while my bottom stays around 55.... what could be the culprit? I have extreme(but rigged) cooling going on.

All the wires are arranged well for ventilation, I have 2 floor fans rigged inline as the case's side fan. 2 120 mm case fans- push pull. A 90mm fan on the hot cards backside, and another 80mm fan.

The entire setup sits with a 10,000 BTU airconditioner that I actually bought yesterday blowing directly into the side fans. Its so cold in this 10x10 room that it isnt funny.The A/C is rated for a 350 sq.ft room.

So I fear something must be wrong with that one card... what could I do?


EDIT: After typing this message I noticed my 2nd gpu was jumping all over the board but stopped after I clicked Save.... This was due to the animations on the thread create screen(smileys) How in the world is that making it hit 20-80% usage wildly?

I got it last march from newegg, would I still be eligible? I think this happens no matter which card is in top though...

wow

seems a bit a hot. what % are the fans at? on my setup i have to run one of my 6950s at a much higher fan % because it runs alot hotter then the other gpu below it. so maybe increase the fan speed on the hot gpu which i guess is the one on the top?

Are your cards non reference or reference?

Yes, it is important.

Well I have them at 100, and no OC going on either.

This is my model http://techiser.com/his-hd-5770-h577...rd-118168.html

1. That card is a non reference card as I thought it would be. Non reference designs exhaust heat inside of the case whereas reference cards push all the hot air outside of the case through ventilation in the back. Thus, right when you add in a second non reference card for crossfire temps will shoot up.
2. That's a really tiny heatsink in the first place.

How many exhaust fans do you have?

All the wires are arranged well for ventilation, I have 2 floor fans rigged inline as the case's side fan. 2 120 mm case fans- push pull. A 90mm fan on the hot cards backside(the side without a cooler), and another 80mm fan.

The entire setup sits with a 10,000 BTU airconditioner that I actually bought yesterday blowing directly into the side fans. Its so cold in this 10x10 room that it isnt funny.The A/C is rated for a 350 sq.ft room.

Where are the fans located?

Could you make a quick sketch in Paint showing us airflow direction?

Reason I ask is because with my non-reference crossfire setup my fans were pushing hot air back into the cards. Moving my entire rig to an open case enviornment gives me 20-30c lower temps across all GPUs.

Seems like in that motherboard has enough space between the two slots. But can you confirm for us if the two cards are literally touching each other inside your case? Also you mentioned it does not matter which card in top. Are you saying either card shoots up to 90c at the top slot or are you saying the same card shoots up to 90c even if it is on top or bottom? Have you tried each card separately by putting just one card in the case to ensure not an issue with the card? Also, are you using MSI AB?
