My gpu heating up to 90C while in load (Sapphire HD 7970 Blower)

[nullgaminggr]

I have an HD 7970 Blower style gpu which heats up to 90C in some games,if i play minecraft it will not heat up above 80C but if i play something else like Steel Oceans or Space engineers at ultra it will heat above 91C (and no framedrops occur), my gpu's heatsink is cleaned and it has thermal paste applied (arctic silver 5) my case has 1 fan and im waiting for the other 4.

Well, 7970 is some years old already and I understand you have cleaned it and replace the compound.
Would suggest to remove the compound once more and apply a little less (or more) depending on how much is on the chip at the moment. As long as the fan works properly you should achieve better temps.

Well,i got it used and the seller told me it was watercooled also i have 1 fan in my pc and no exhausts,my only exhausts are the gpu and the psu and im waiting for the 4 other fans and i don't have any spare thermal compound left at my home

Uhh...very little ventilation man. At least for me it is always worth to have some compound at home. MX2 costs around 2-3 bugs and is really good and easy to apply. Buying a metal compound might only bring 1-2 C and therefore is not worth the additional cost.

Which GPU is it exactly? Any picture from the inside of your case you can share?

Well it is an HD 7970 Blower style made by sapphire plus my cable managment on the lower part of the case is not so good
