R9 290x crossfire

[evilmeister13]

I have a buddy who wants to sell his two stock 290x cards for $150 each and i want to jump at the chance for cheap cards, but im worried about heat. I have my i7 5820k watercooled, but idk if both cards would be cool enough in my NZXT phantom. Should i upgrade my case or should i be fine? I really dont want to buy two cards if theyre just going to throttle constantly.

Yeah they should be cool enough

Ill have headphones on that block 99% of noise around me. Will i have to put on a custom high fan curve or could i leave it at stock?

Well you see, I had no problems keeping 2 290Xs at 75C max 40% fan speeds but that's with sub 15C ambient temps so...ermmm....

 

Anyway, if I remember correctly drivers should automatically set fan speeds to 60% underload where the 290X will not throttle at all even in high ambient temp situations.

Well...which reference cooler isn't shit? Why can't AMD and Nvidia just steal HIS's IceQ blower design for the 7950/7970...

Don't be scared of 290x temps, its a bit hot but they are designed that way, so you'll be fine.
There just a bit noisy and you wont need a heater in your room anymore in the winter, that's all.

Damn, the AC in my house barely works (sits at 93 degrees F) and im sweaty af most of the time as it is. Cant wait to accept death in exchange for more performance.

Ul be fine

Can I ask a similar question?

 

I have two Sapphire R9 290x 4Gb in crossfire in a mid tower case.  I am finding when running most games the lower of the two cards is running very hot.  The cards have LEDs that turn blue/yellow/red with red being upwards of 80 degrees.   The upper card remains blue and appears cool even when running Heaven.   I've also noticed that if the display port connection is switched to the upper card then this one heats and the lower is fine, so this seems to be an issue relating to which ever is the primary card.  Please note that the case is well cooled with multiple fans including one aimed directly up at the lower GPU.

 

Question:   Is this normal in crossfire?  Does it indicate that the crossfire is not setup correctly?   Can I possible fix it?

[DXMember]

by stock you mean reference blower cooler?

 

you'll be just fine, if they get hot it's not a case issue it's the cooler issue, if you can grab an aftermarket cooler on ebay or something

[DeadKerbal]

Apologies, I should have clarified.   Both the cards are identical Vapour X models that are already after market cooled.  I wasn't sure if them running 80+ was normal.  here's the cards:
