GPU temps unnaturally high

OfficialG3 · May 23, 2017

Hi, i have a gigabyte R7 260X oc 2gb ddr5 (have a powercolor one too as a point of reference), its on the single fan design, and weirdly enough the temperature on a single superposition bench reaches 93 degrees, 7 degrees from boiling,(on factory set speed) anyway my powercolor one only reaches 80 - 85 if i really push it on a 1225mhz core, now how can i "fix" this ? i recently changed the paste to something rated at 5.15w/mk (from ID-Cooling), both cards are running the same paste, and idling temperature is somewhat the same (40 c ish)

is it because this card has a "shite" heatsink ? since its just all-alluminium with little effort put into it with a 2500rpm fan compared to my powercolor 3000~rpm fan and alluminium fins + copper piped heatsink ?

While 93'C is definitly on the higher side, that can be a tradeoff for a single-fan design.

I assume your PC card is a dual fan card? So temps are not really comparable.

I'm not 100% sure of the 'max' temp for a 260X, but IIRC it's right up near 100'C.

Are you experiencing any throttling or artifacts on screen?

A simple "fix" (in the loosest use of the word) would be to downclock.....but I suspect you're fine 'as is'.

To be sure, can you check out the thermal margin in AMD Overdrive?
That'll measure "degrees to zero" ie degrees until shutdown (throttling usually starts around TM of 10'C)...... I believe OD can still be utilized for this anyway, haven't used it since I had an AMD chip/card a while ago.

Barty1884 :

uhh no, both of my r7 260x are single fan designs, this gigabyte one just have the "hot" temp issues
i know that the max limit of these cards are 97 but that is just so close near the level of "im not cool with this"

What does your case & airflow look like?

OfficialG3 · May 23, 2017

Barty1884 :

Case is a local rebrand of the Rosewill - Black Gaming ATX Mid Tower Computer Case (SAMA OEM)
All fan ports used
front side is using a generic led fan pulling air in
side panel fan is using a delta fan pulling air in
top side is using a generic fan exhausting air out
rear side is using 2x delta fan on an AIO radiator exhausing air out
doesn't seem to have some problems with airflow tbh, been rolling like this for about 6 months or more

Poor case Airflow it sounds like to me. In sli or crossfire (usually the top one) one card will always be hotter due to the other restricting its airflow. This is normal. Get a better case and some good case fans.

I don't think that the case is causing the high temperature

Barty1884 · May 23, 2017

The case is a tough one to test, but the CrossFire aspect could be.

Try removing your second card, leaving only the 'problem' card in there are run some stress testing - how do temps look then?

Barty1884 :

Yep this is my next suggestion and what I was referring to earlier in my suggestion.

i never said i have ran then in CF, i am single-testing the cards, my CF compatible board is coming some time soon, maybe when it arrives ill just put my Polor card ontop

OfficialG3 :

The card on the top has to suck up the hot air emitted by the bottom card.

& thats the reason i pick the polor card ontop

Then you dont need help afterall it seems...

hmm maybe, is aftermarket cooling worthed or not ?
