One 390X is comparable to a 980ti on some DX12 titles, just for reference.

3 cruising 390Xs = 2 980TIs at their peaks.

Im not sure if you are agreeing or correcting me? I did said Dx12 though. I wasn't talking about benching or dx11. And this is all very title specific as well. Just in case it was a correction. Lol no worries either way though. You bench more than I do, so I know you are more up on it than I am.

DX11 already shows 3 290Xs beating a couple 980TIs. Imagine DX12 where AMD's compute power can play a lot and utilized to their potential. thumb.gif

No nVidia card can beat 2 290X at the moment. Be it DX11 or DX12 to call it short.

Yes. Agreed.

But even on DX12 one 390x is doing as well as the 980ti on some benchmarks. On 4k that is anyway.

No denying these cards tbh.

And yep, I have little faith with reviewers. They are paid by honchos.

OCN end users are better sources.

Hello all!

Wish I had found this page under better circumstances but I am hoping you guys can help me turn it around.

I can't keep my MSI 390x from throttling. It quickly jumps from low 40s to 94 and throttles within 10min of gaming. I know its an airflow issue because it drops to 80c when I remove the side of the case, but I can't figure it out.

I have an inwin 703 with:

- two 120mm intakes on the front, a stock case bottom fan (obstructed by immobile HHD cage) and a Noctua NF-F12 on top
- InWin stock exhaust fan remounted as bottom intake (not shown in Pic)
- One Thermaltake Riing 12 exhaust
- CPU is cooled by Noctua DH-14 pushing toward the exhaust fan

I have already reapplied thermal paste with Noctua NT-H1.

The CPU is great and stays at 30-40c, however the GPU just dumps heat into the case wall (I can feel at wash of hot air coming from the space between the fans when I hold my hand up to it, and for some reason the unobstructed NF-12 isn't pushing it out .

I am considering cutting a hole in the case wall and mounting a 120mm intake, and if that doesn't work just watercooling the whole system, but I'd rather not spend that kind of money at the moment.

I have tried mounting it in the other PCI slot to no effect.

If applicable I live in a high desert, 5000ft above sea level in Arizona.

Sorry for the disjointed post, just trying to answer all the anticipated questions.

Insert the card on the First PCIe slot. - that should give the card the needed breathing room. Plus, can benefit from your intake fan at the middle of the case.

Set a higher RPM profile to the GPU. As long as you can live with the noise that comes with it.

Use higher static pressure fans. (High static pressure for case fans -- am I nuts?) That can ensure you get enough air flow considers a small not very ventillated case.

Visit the hawaii bios editting thread. You might be able to get some tips on how to undervolt the card. Less Voltage, less heat with the expense of a little performance loss.

Positive air pressure is good. But you might need to use optimisations to fully exploit the benefits of a good case air flow. Rear fan needs to be a bit faster to pull those hot air out the case.

Is it worth the premium for 2 390X crossfire against 2 390?

Imho, No.
2 390s only need a 1050 PSU (Minimum) (I have them running on a Corsair AX850, all fine, except I dont want to test any GPU stresstests, pretty sure the test would sap way more than 900w causing my PC to shutdown, but 390CF on a 850W works fine gaming Witcher 3, Crysis 3, Black Desert, all fine, can play hours)

whereas 2 390Xs would most definitely need 1200 at the least.

in gaming scenarios, most games only gain 5-10fps going 390 to 390x.

if you think the PSU and price of 5-10fps is worth the almost $100 extra, than sure, 390X CF is fine.

My psu is a xfx 850w black edition.
80 gold tier 1.
Would it handle 390 crossfire?
