Cooling GPU

Rensin · 16 Sep 2015 at 12:09

Hi,

Have recently installed a MSI 390x and during gameplay the gpu temperatures are reaching 90+ and was wondering if anyone can advise on lowering these temps. Overclock has been removed so everything apart from custom fan curve is default.

Room temperature is approx 25-28 degrees.

All fans are 140mm except the rear which is 120mm. The fan at the side GPU has been removed as made no difference to the 390x.

thanks

First thing I'd do is reverse the rear fan to exhaust.

I thought this when I moved to the 650D but upon installing the H110 a lot of members on the corsair forum recommend to have the rear fan as intake and rather than exhaust.

Will a fan on the floor of the case make enough of a difference to warrant cutting a whole into the floor of the case? (similar to the PSU cutout.)

install msi after burner and do a fan profile
remove heatsink and apply own paste

not sure which cooler your sapphire 390x has if it's a leaf blower style then that explains the high temps
Airflow is never going to make that much difference it's all about the quality of the cooler on the chip

MSI Afterburner is installed with a custom fan profile set which is working as it should.

It's a Vapor-X from the looks of it?

Picture above was taken a few weeks ago and GPU has been changed to a MSI R9 390X which has the Twin Frozr V Cooler

ok will reverse the rear fan tonight and test.

thanks for the help.

Didn't get round to testing tonight so will test tomorrow.

The H110 rad will only fit the 650d case with the fans on top due to the external hard drive mount.
If it will make a difference to Temps than I will cut part of the hard drive mount so the fans will fit below the rad.

Rear fan reversed, top external drive mount removed and H110 fans installed below (pushing air through radiator)

Have managed around 10 minutes gaming and max gpu temp was around 58 degrees :eek:

... wow big difference thanks for the help :cool:

.

Have a problem of after 10 mins in a game, the game will crash with a Black screen, my second monitor still works showing temps ect and either need to restart PC at socket or ctrl,alt+del and end task. I know my RAM is OK as only have 2 sticks installed and both have had 6 hours each in memtest. (tested separately). Have also tried both the latest AMD driver & beta.

Any other ideas?
