780 Windforce running hot - potential upgrade too?

Hi all,

My younger brother is using a gigabyte 780 Ghz Edition with the windforce cooler (triple fan).

He's been complaining lately that the PC has been crashing under load, and recently wouldn't turn on at all.

I tested it on furmark, and fans quickly spooled up to 70% and about 92 degrees under load, drops to about 1040 Mhz on the core - this seems excessive to me. It's a pretty well ventilated case, with 2 intakes and 1 exhaust at reasonable speed.

The PSU is a 650W EVGA GQ. Not the best PSU I know, but should more more than suitable for this GPU.

When I turned on the PC recently, the first time since he said it wouldn't turn on at all, I was greeted with a BIOS message saying that the overclock settings weren't working, so I reset it.

It's running an i5 4460 too, so it shouldn't be overclockable. My initial thought is RAM - it's running XMP.

To summarise:

  • GTX 780 Ghz Edition (Gigabyte) hitting 92 degrees in furmark after 30 seconds, fans about 70%, core about 1040 Mhz. System then proceeds to lockup and reboot required.
  • i5 4460, 8GB DDR3 @ 1600Mhz.
He often complains that performance is poor in fortnite, often sub 60 FPS - this seems strange for me, as the 780 is still an okay card for 1080p gaming.

Any thoughts would be greatly appreciated :-)
 
I still have my 780GHz in another machine - no way it should be running that hot and mine is running something like 1289MHz or something I'd have to double check.

I upgraded to a GTX1070 which was a fairly decent upgrade - so anything around that speed or faster would be a good upgrade - though the 4460 will become a bottleneck for anything faster than a 1070 and some more modern games like more than 4 cores/threads to run smoothly.

I'd run memtest to rule out the RAM.

EDIT: Looks like Fortnite is fairly CPU single thread heavy and so once you get to about GTX1070 performance or above at 1080p you don't gain massive amounts from faster GPUs and as such will be fairly CPU MHz sensitive.

Wicked, thanks very much for the info :-)

It's been a while since I've done all the testing stuff; I became so fed up of things not working that I transferred into the "plug it in and leave it" club; I like my things to just work now.

I was thinking of something like a 2600 - would be a decent upgrade I would imagine?
 
@Rroff

A 4770K at 4.5GHz with hyperthreading disabled in Bios to make it just four logical cores is a bottleneck for a GTX 1070 in Fortnite at 1080p and will hit 100% CPU usage practically all the time and cause stutter.

@MrRockliffe

Seems the paste on the GTX 780 may have dried or been squeezed out and/or it needs a good dusting.

I'll give that a go and see if it helps :-)
 
Had to replace the thermal paste on my vega 64. Think the recent hot weather has caused this
 
If that bios message keeps popping up regarding overclock settings it could be that the cmos battery is on the way out and needs replacing (CR2032).
 
Once reapplying the thermal paste, just make sure all the thermalpads from memory chips and other essential areas are in place before putting all together again.
