My friend has a XFX R9 290 reference model and he got tired of the abnormal noise. He wanted to sell it ASAP and get 1060/1070.
Somewhere in my closet i had my 280X that died half a year ago and i was interested if cooler from 280X would fit his 290. The fact that they both are from XFX gave me more hopes. I never expected lower temps we both wanted less noise, nothing else.
So he brought it here and we took both of them apart.
280X DD cooler fits 290 perfectly, but the only problem was the fact that 280X heatsink does not fit GPU perfectly.

Yeah, we were worried that it wont cool properly, since heatsink doesnt cover the GPU die perfectly. But we tried anyway. Yes, we are crazy.
Reference 290 temps are about 35-40 idle and from 85-94 in load.
So we started the pc up, idle temps were sitting at about 38 degrees celsius, with fans on 20%.
We overclocked to card to 1175/1425. 1.25v(+30mv) and we set fans on 100% just in case.
Then we started Unigine Heaven on ultra preset.. Max temps were 71, and thats after 10minutes of benchmark. they mostly were at 66-69 range. We were shocked, so we tried few other things.
Furmark - same thing as heaven, temps never went above 70
So we set the fans at 80% and ran some games, all games were run on ultra preset 1440p
Witcher 3 - 70 degrees max temp, dropped down to 65-68
Battlefield 1 - 69 degrees max temp, dropped down to 66 sometimes
Rise of the Tomb Raider - Same thing as Witcher 3
VRM temp sensors in GPU-Z said that VRM1 temps were 84 max, and VRM2 had max temperature of 54 degrees celsius.
We were shocked and we left Heaven run for a few hours, temps never exceeded 74 degrees.
So we tried with Automatic fan control, then again heaven. max temp was 84 degrees.
Temps were monitores via GPU-Z and MSI Afterburner, also with Heaven benchmark info.
He just took the PC home and enjoys it since it literally makes no noise.
But we both are not sure what to expect.
GPU die has some thermal paste on the areas where Heatsink did not cover it, not sure if that helps.
But there is no artifacts, no throttling, nothing. Overclock is perfectly stable.
What do you think about his experiment ? i hope we are not the only ones who tried this.
