R9 390X high temps

[Piotr_10]

Specs: I5 6600k @ 4.3Ghz
16GB DDR4 Ram @ 2400 Mhz
R9 390X DD

I had my R9 390X for over year and a half. The card always preforms amazing I can play any game maxed out.
Lately the temperatures where getting high up to 85C. I never had this problem before would re-applying thermal paste over the stock help to bring the temps down ? Could anyone recommend best thermal paste for the GPU

Yes it will definitely help if u replace thermal paste. I bought GTX 1070 1 month ago and then replaced it right away, got down by 8C. And you have used your gpu for over a year. I believe that some brands use cheap pastes from the factory. I have used cooler master essentials E1, not the best but did the job. http://www.tomshardware.com/reviews/thermal-paste-performance-benchmark,3616-20.html check it here. Make sure u get non conductive to be more safe.
Also u could try to clean your gpu from dust first.

First clean the GPU cooler so there is no dust or dust bunny's
Do the same to the case and case fans
next ensure there is enough air flowing through the case to keep the GPU cool

only after all of he fore mentioned should you look at changing the thermal paste. Never put paste over paste. Always clean off the old paste and reapply new never mix them. Look into Arctic MX4 thermal paste iff you find you need to reapply.

EDIT: the both of you need to read this article. It will explain why your temps dropped so much: http://www.tomshardware.com/reviews/optimizing-graphics-cooling,4838.html

I agree with bgunner. What case do you have everything housed in?
Also what games were you playing a year ago?
What games are you playing now?
Perhaps newer games are putting more of a stress/load onto your gpu.

1. AMD is on record as saying that have no issue with temps at 95C.

2. GPU cooling is largely dependent on case cooling. If noise is a concern, one 120mm fan for each 50-75 watt5s (75-100 for 140mm). If you don't care about noise, the 75-100 watts for 120mm (100-125 for 140mm). Your 6600k at max OC (135 watts}, 390x (375 watts), 35 watts (MoBo), 40 watts everything else ... so you are looking at 585 watts ... so (6) 120 mm fans as a minimum.

3. Ideally you'd want to split then (4) in and (2) out ... Intake filters will steal up to 1/3 of the flow rate so 4 x 2/3 gives you more iair in than out meaning you won't be sucking dust in thru rear case grilles. And what comes in w/ that dust ? All the hot exhaust from your PSU and GFX card.

4. The best Thermal paste available at a reasonable price is Shin Etsu 751G ... it took the crown back in 2009 and the only real newcomer to the scene is Grizzly and the top end product is a bit better but it's 5 times the price. There's also the Liquid metal stuff but that's not recommended for the npvice.

You will see that AS5 tied Shin Etsu in thermal performance but AS5 costs more than twce a smuch ans it has two major issues:

a) It takes 200 hours to cure ... that's about 6 weeks of typical computer usage. ... see advisory on AS5 web site
b) It is capzcitive ... see warning on AS5 web site

5. Keeping the fins clean is essential, more so than paste. Take of the shroud, hold then fans with your finger and blow out dust, cat hair, whatever from between the fins.

6. I use Indigo Extreme Surface Cleaner but if not available, a trip to Walmart fir 90%+ % bottle of isoprophyl alcohol is a decent substitute to clean off old before applying new. Also be aware that the GPU is not the only concern here, the VRMs and memory chips also require cooling and you should make sure that all thermal pads are re-coated with TIM on both sides if used.
