Too hot for my 390x?

I've been playing around with Virtual Super Resolution this weekend and I noted that my 390x crept up to 89c when playing sleeping dogs at 1440p maxed out (normal AA though) at around 60fps. Is this too hot? It's not as bad at 1080p @60fps as it isn't working as hard, but it's 80+ on most modern games...

I'm not sure If it is the ambient temperature (it's probably 25+ in this room as it has the water boiler/airing cupboard, plus the outside temperature) or just a hot card.

It's the Double Desperation edition.
 
That is on the higher ends, from what I've seen with 390's and from reading reviews of the 390x low 80s are to be expected. Not that your temperatures are getting into dangerous territories just yet.

How's your case airflow?
 
I suspect airflow's your only issue. Try taking the side of the case off for a while and seeing if that makes a large difference. Also, do you have a custom fan profile that's not taking the fans up to 100%?
 
I was considering re-pasting my MSI R9 390, the card had been getting to 94c @ 100% fan and throttling in titles like Rise of the Tomb Raider.

Now I'm not so sure its the paste and rather that my case is rubbish at shifting the hot air (1st gen cm690), as the temps drop to ~79c at a much lower fan speed with the side off.

At this point I'm considering getting another case with unrestricted airflow - the cm690 gen1 has a lot of non-removable hdd bays at the front.

In summary it's worth giving it a go with the side off to determine if your airflow is the culprit.

SD's was/is one of the toughest titles to run on AMD as it was fine tuned and iirc very shader heavy, so your card is working really hard in this title.

XFX DD cooler to run was designed for lower noise/profile rather than lower temps but remained within the 90/5c threshold.

It could probably be improved, I have one inhale and one exhaust (plus my PSU, but in it's own compartment). Also a H100i pulling air into the case, over a rad.

That's a major cause for increasing your gpu temps, you are pushing hot air down onto your gpu, I'd highly advise mounting your fans under the H100i to push hot air through your rad and vent all the hot air and it'll vent some of your 390 heat too.

I've got space for a 120mm up top (next to the 240rad) and a second 120mm on the front. should these both be inhaling into the case?

Use that 120 up top to vent out next to the H100i add your second 120mm as intakes to suck cool air in the front and it'll feed cool air to your gpu and the 3 120's all sucking the 390X waste heat out through the top of your case.

Something like this:

IMO do all you can to keep temps down, as in, setup the intake/exhaust fans as tommy suggests, setup a more aggressive fan curve and repaste it too (msi is one of the ones that keeps popping up as poor application/way too much paste, but all could suffer from it, so worth doing most of the time).

I have probably one of the poorer cooling 390x and I am not seeing temps above 80 (even when crazy enough to try and break the card with furmark).

I'm sure if you do all the above, yours will fair better.

With the case fans on the turbo profile, the case panels off and an extra inhaling fan (plus lower ambient temperatures), I got 69c, very happy!

It turns out I can't mount a third 120 fan up top as the rad is too big. But i'll flip the H100 fans.
 
Also try undervolting with MSI afterburner, it makes a drastic difference in temps and fan speed for my MSI 290 gaming edition, mine is set to -31mv
