Sapphire R9 390 Thermal Pads/Paste?

[demonic186]

Hey,

just wondering if anyone has any idea what thermal pads and thermal paste would be a good upgrade for this graphics card?

currently on idle it sits at 35-40C with GPU Fan speeds at a constant 35% (not auto mode) I found auto mode SUCKED and would rev the fans up and down from 20% to 65% instead of keeping the temperature constant.

on full load in most games the temp rises to 65C with GPU fan speeds around the 55-60% mark, if on auto mode however the temp rises to 70C+ with GPU fans at 40%

Should note that the intake fans are at full RPM when gaming and lowest speed possible when idle and the exhaust fans - push-pull radiator fans running at 50-60% speed gaming 1600RPM, 30-40% idle - 900-1100RPM

Although that sounds OK for this graphics card there has been the rare occasion when the temperature on idle has spiked to 80C when I boot up the crimson software though it does lower again, which of course got me worried that perhaps the paste and/or the thermal pads haven't been applied correctly.

I've been hunting and googling galore and reckon I'll go with arctic mx-4 paste though some advice would still be nice - I haven't ever really replaced thermal pads before or had too so that's the main area of concern.

Help appreciated

check this thread about 390 thermal paste.

The temp spikes are almost certainly a software bug and nothing to worry about. HWMonitor often tells me that my gpu reaches 255C which I know for certain it isn't.

New thermal pads won't affect core temp.

I wouldn't spend a penny on it. 390's and 390's are hot running GPU's, almost impossible to keep them under 80DC on air without having the fans at a deafening setting. Nothing you can fit/change on the card will reduce the immense amount of heat it outputs.

It's worth remembering Hawaii GPU's (290, 390 series) are all designed for 92°C+, so 80°C is a very safe temperature for these cards. Nothing to be worried about at all.

I'd enjoy it's performance for now and then upgrade to a 16/14nm GPU when you feel it's time.

cheers for the response + advice, I've heard that these cards can run hot and were designed to withstand such temperatures but it's still nice to try avoid those temperatures.
