Hey guys.
I've had this problem. My 2 R9 290X'S are Watercooled in there own separate loop with a 240mm radiator with 4 fans in push pull config. And somehow they are reaching 80c At stock clocks and voltage. I've redone my thermal paste today on both cards and still at these high temps. I use MX-4 thermal paste. Any Ideas why they are so hot?

These cards just run hot, end of story 80c is a pretty big performance over 95c with stock cooler. Also mx4 does not work on those gpus due to its cure time and viscosity. it just completely liquifies it and you lose a lot of contact. gotta use a different thermal paste (saw this in another thread, and with the right paste, got 15c lower vs the mx4

I know they run hot. But this is stock clocks! 15c is hardly a change from the TERRIBLE reference cooler, This is a waterblock it should at least max out at 60c. Everyone else with a 290x with waterblock get there temps down to 50c ? I was recommended to use this thermal paste by countless reviews and when I pulled the block off yesterday the paste was normal. Any other ideas?

no, that paste simply does not work for some unidentifiable reason. it's a great paste for anything else, but for the 290x specifically (hottest gpu in quite a few years) it simply did not work for the other guy, while some other brand gave him 15c lower temps. it's the thermal paste, i just don't have the time to go back and look for the thread.

only other thing would be a defective pump, or not enough pressure of the waterblock on the gpu.

i doubt it's the pump if you have a full custom loop otherwise you'd notice, and i have confidence in you being able to know how to install a waterblock. therefore the ONLY other thing can be the thermal paste, which i have been in another thread where someone had this exact problem with that exact thermal paste, and it was remedied by changing to a different thermal paste.

and that would be 15C lower than your 80c, meaning down to 65c

I personally use mx4 on my cpu, so i'm not calling it a bad thermal paste, but for some ungodly reason, it does not work well on the 290x specifically
