GPU running at insane temps

For context, My son plays nothing other than Fortnite, spec of his PC below (PC specialist build from new).

There was an issue with a failed fan on his GTX960 so I took the opportunity to upgrade my GPU and donated him the GTX 770 GPU from my PC when I upgraded to a Vega 56. In my rig, the GTX 770 performed flawlessly and never skipped a beat.

My son has to limit FPS to 30, even on medium settings, otherwise his PC goes black screen and have to force shut down by holding down the power button.

I've taken a look today and did notice the temp inside his PC is quite high and he only has one Corsair case fan which was running at a very low speed so I've gone into the BIOS and forced it to max speed to see if that helps.

I then installed MSI Afterburner and again, forced the GPU fan speed to max for anything over 60 degrees.

Before loading Fortnite, this did have the effect of reducing the GPU temp by maybe 1 or 2 degrees per minute but it was already in the 70s, probably because he had been playing Fortnite for a couple of hours (albeit at low settings and 30 max fps).

In Fortnite, we then set the gfx settings to recommended which pretty much set everything to medium. We then overrode that by changing the view distance to long.

Not sure if it's relevant but he has a 120hz monitor so the refresh rate is on 120.

When we started a game in fortnite his GPU temp was in the high 90s before we even started running around & building etc.

MSI Afterburner then showed as high as 104 before the system shut itself down with blackscreen (although PC was still turned on with all lights / fans spinning).

I was of the impression Fortnite isn't the most demanding game so was very surprised at how badly his PC was performing. Airflow in the PC isn't the greatest but still, I'm wondering if there is more too it? CPU temp was fine so it definitely points to the GPU but again, the GTX 770 never let me down once in the 4 years I used it so would be surprised if it's a hardware issue with the GPU.

I've bought an RX590 from the special yesterday, it's for his birthday in a couple of months but I don't want to give it to him now. I am worried whatever has caused the GTX 770 to overheat may happen again with the RX590.

Any advice much appreciated as always, thanks guys.

Case - Corsair (can't remember!)
Mobo - Gigabyte Z170-HD3P LGA1151
PSU - Corsair Vengeance 750M Silver
CPU - Intel i5-6400
RAM - 8GB DDR4
GFX - MSI GTX 770 OC 2GB DDR5
Monitor1 - Samsung SM2233RZ 22" 120Hz
Monitor2 - Generic 24" AOC
 
You need minimum of 2 fans
1 intake 1 exhaust
May be something else going on too
Take the side panel off and play
What happens then?
If it's OK then it's airflow problems
 
Are the fans running properly?

Have you blown the dust out of the Gpu lately?

If none of the above helps then you could try taking it apart and repasting the Gpu die
 
To be fair we had the side of the case off but the temp was still very high inside, that said it's fairly warm in his room.

Agreed it can't hurt to invest in a few more case fans, I'll definitely order a couple, given I don't qualify for free delivery I'll probs get a pack of these ***competitor info removed***

Anything else you can think of? Still surprised how high the temp of the GPU is given the relatively low settings.

Also tried the MSI Afterburner benchmark and again that caused the GPU temp to spike and blackscreen.

If it's getting that hot that quick likely just needs some new thermal paste, being an old GPU it wouldn't suprise me if thats all it needs.

It's possible to be the case but id have expected other components cpu etc to be getting hot aswell.
 
Take the side panel off so any case airflow issues are greatly reduced, and inspect the GPU fans to make sure they are running constantly and don't stall now and then.

Thermal paste may have dried out/been squeezed out after all these years. Thermal pads may have dried too. Dust build up on fans and heatsink. Bit of maintenance/inspection would be good.

If you manage to rule everything else out, it could be his power supply sending too much power to the GPU. Can't remember reading of this happening but I suppose it's possible even if rare. Or a dodgy PSU cable or something. Or the actual voltage regulation on the GPU itself.

You should stick it back in your PC again, to see if the issues are resolved by doing so.
 
Thank you for the replies guys, really appreciate you taking the time to help.

Dust build up could be an issue, on the outside of the case where the single (intake) case fan lives is a mesh grille (I guess to prevent sucking dust into the rig). It was completely pitted with dust - I spent five mins removing it all from the outside mesh with a plastic pencil (the mesh is behind plastic grooves). I'll remove the GPU tomorrow and give it a proper clean.

Re. thermal paste, it's something I'm not confident I would be able to tell if it was good or bad.

I'll order the case fans on prime and fit them, any recommendations for setup (i.e. which ones should be intake and which should be exhaust) and also will there be enough connectors from the PSU to power them or do I also need to buy some splitters or something?

You should grab a can of compressed air and give the Gpu a good blast out ideally every 6 months or so as it can get really blocked up and this can cause temps to rocket.
 
Adding case fans may lower temps by a few degrees but if the Gpu is hitting 100+ then the issue will be the Gpu.

I'm hoping it is just the GPU as that will be replaced in 8ish weeks when it's his birthday with the RX590 I bought yesterday from the OC deal

I'll definitely do that when I order the case fans
 
The motherboard has 3 system fan headers. Plug them into those.

Thermal paste - you just clean and re-paste and test. Don't worry about eyeballing it. Use non-conductive paste like Arctic MX-4 for example. And cover the whole die. Watch some vids on GPU thermal pasting before doing it.

yes quite possibly
but since they only have 1 fan the fans are needed anyway
between more fans and a good dust removal from everything
might just do it if lucky

We don't know what case it is. Take some pics. Usually one or two intake at front and one exhaust at rear is sufficient but it depends on the case.

should pop the front of the case off
to dust properly may be a dust filter in there thats
clogged up

May want to remove the address. Most on this forum are a decent sort (I think) but never know who's lurking with intention to troll or worse.
 
Just to give some closure for anyone that cares, I ended up buying & installing two more case fans so he now has two intake and one exhaust which has helped the airflow no end.

We also took the case apart and gave everything a clean, removing all dust from the mesh grilles etc.

I also noticed an exhaust fan underneath the PSU that should be blowing hot air out of a grille on the underside of the case - as his PC is stood on carpet I'm guessing this was completely blocked so we have raised it up off the carpet.

Also installed the RX 590 8GB as an early birthday present and my son is happily running at 120fps on epic settings so is really pleased.

The only downsides so far are the RX 590 only has HDMI & Display Ports so we've had to use an old DVI to DP adapter I had in the spares box which works but can't handle 120hz so his Samsung 120hz monitor is running at 60hz for the time being.

His second monitor (which is really old VGA) was previously on a VGA to DVI adapter on the GTX 770! I've tried using the VGA to DVI then a second adapter DVI to DP but it doesn't work so will have to pick up two new adapers for him (one DVI to DP that can handle the refresh rate and one VGA to DP or HDMI).

If anyone has had these issues before and can recommend a solution I'd appreciate the advice, failing that will just google!

Did you check if graphics card's cooler was clogged by dust?
Especially in cases without filters insides can get really dusty after few years.
