wierd 290 cf behavior?

[Nrøjbrot]

well, i noticed that when i just use my computer normally, like browsing the internets and such. the gpu ramps up every now and then, seemingly randomly. is this normal? or should i investigate further?

here is a picture of the spikes:

 

 

and here's something else i noticed: (this is in heavenbench)

+ they reach 75 c idle....

Your first question is yes. opening something in like a browser will require some GPU power so it fluctuates, and the second one is a bug that heavenbench has for some reason.

Well, i believe insane idle temps is quite normal with the stock cooler

The fluctuations are normal but 75c idle IS NOT normal. I have a reference design as well and mine drops to 40 or lower.

i doscovered somthing else too: this is from playing bf4.

and in heaven bench i get this

[Nrøjbrot]

i'll try to test with one gpu and see if there is something wrong with one of them

the R9 290/R9 290X are designed to operate in a much higher themal temperature than most graphics cards

Problem solved!! the new drivers fixed everything oddly enough... i have no idea why the idle temps dropped tough.
