The readings up to 90 deg, still had Fortnite app open, but not being played. When that was closed the dropped quite quickly and the fan shut off. So I'm going to test before, during and after a Fortnite session. What's a realistic high temp in a gaming session expected to be?

Yeah, maybe shouldn't have removed the heat sinks, but it was difficult to get fans out with heat sinks in place.

If you didn’t re-apply thermal paste, then yes take it apart again to clean and re-apply.

If the fan is wobbly or seems to be at a low rpm you may need to replace or take it fully apart to check the bearing (if applicable). Or just be careful when putting it back together that it isn’t scraping the shroud when in operation.

It’s been a while for the HD5870, ideally you want to be in the lower 80’s for temperature. If you’re in the 90’s now just idling then come summer it’ll start cooking.

So I ran a log over a gaming session. The GPU temp got up to a max of 107 deg C. The GPU clock went up to 780 MHz when the gaming started, but pulled back to 730 MHz when the temp got up. So I guess I've got a fan/temp issue, including the noise. I could try to fix the fan and the thermal paste, or I could replace the fan, or I suppose I could replace the card with something new and higher specced. Where's the best bang for buck here?

the latter option

almost anything beats your current card

a $1 tube of thermal paste is your best bet

The M83 PSU is only 280w so upgrade that as well. For now remove the side panel on your case which will drop the temps down a bit.

Tbh I didn't think Fortnite was that resource heavy....

I just read Fortnite is developed with Unreal Engine 4. I'm playing Panzer Corps 2 which uses the same engine, and my 280x is always pegged at 99%,. So I guess it it is resource heavy.

Yeah that GPU is overheating.

Anything over 5 years old is going to want thermal paste replaced if its showing excessive temps like yours is.

Does the current GPU have a power cable plugged into it or is it just powered by the pci slot?

The PSU's in these types of PC's are usually the limiting factors as to what you can put in as far as new GPU's are concerned.

You might be able to get away with a GTX 1650 or a 5500XT.

There is something else that could be a free fix. Look up the brand and model of the card and check for a VBIOS revision, (you can check the vbios in GPUZ) Some cards have heat issues that were bios related.

Earbanean: OK, after a really good clean, including taking off and cleaning each fan and heat sink (and especially the huge amount of dust caught at the inlet fan), it seems to be running OK now. My son played Fortnite for over an hour and no shutdown. However, I noticed the fan on the graphics card is a bit noisy, so I had a quick look after that with HWiNFO. The GPU got up to 90 deg C, with fan at full speed and that wasn't while he was playing. I think it might be worth replacing that fan, if for no other reason than the annoying noise. Would it also help to redo thermal paste for that as well? There didn't to be much and it was probably dried out, come off. Note the main CPUs were only 30 - 40 degrees, so I don't think any problem there. I'll monitor/log temps and speeds this afternoon through another Fortnite session to check these and the GPU under more load.

Great!

A few drops of light oil should do the trick. Underneath the sticker.

One drop, or better yet if you can take it apart and clean any gunk and just lube the fan shaft. Too much and you’ll get oil spray all over the shroud, heatsink and motherboard. i speak from experience :)

I think I'll try the thermal paste and fan oil approach first. Replacing the graphics card will probably require replacing PSU and that starts putting it in the too-hard basket for a PC that's not primarily intended for gaming. If that doesn't work, then I guess I go down the new card and PSU route.

Any oil in particular for the fan? I was just going to grab some sewing machine oil.

Just powered by the slot.

Yes, mineral based light oil aka sewing machine oil. Definitely not vegetable based like 3-in-1, which for some reason seems to attract dust.
