GTX 780 overheating/running correctly?

lbPC · Jul 29, 2016

So this is probably a very ignorant question however I just dropped some money I'd been saving to get a GTX 780 (I know its an old card but its a big improvement for me) and am just worried about it overheating or not running properly?

My rig is:

CPU: i5 2500 3.3GHZ
GPU: GTX780
RAM: 8gb
PSU: Thermaltake Litepower 700

I've looked at the temp when running games and it usually bounces around 70C and 80C, however it doesn't seem to change much if I up the graphics to the highest or the lowest. Every now and then my screen will freeze and kind of re-start, however I'm still getting 70+ FPS on things like Paragon, Lawbreakers and Evolve. The freezing has only happened to me tonight whilst playing on American servers with around 200ms or higher.
It also runs more loudly than I'm used to and basically I'm just worried that its going to overheat and break or something?

I only have one fan at the top of my pc and it's just a mid-tower with an mATX MB if that affects anything.

Finally, when connecting it it needed one 6 pin and one 8 pin power adapter. My psu has two 6 pin and one 2 pin, so I used that to make an 8 pin.
Is that correct?

Sorry for all the questions, any help would be appreciated!

Okay thank you!
I read something about 80C being the temperature roof or cutoff or something for the 780, so does that mean it doesn't let itself get hotter or what happens?

I wouldn't be overly concerned about 70-80C on a GTX 780. On my 780Ti SLI system my top card runs that hot or a little hotter depending on the game. If you have the card overclocked I would reset it to stock settings; the screen thing could be your graphics driver crashing so you might try the preceding driver if you're on the latest one and see if that goes away.

I would recommend using something like MSI Afterburner to set a custom fan profile though.

Okay will get afterburner!
I bought the card secondhand so I have no idea if its been OC'd, how would I check for that?

If it hits the thermal roof it'll start throttling, which means that you get drastic performance decreases. The GPU is trying to save itself by doing less.

So that screen thing isn't this?

Shouldn't be seeing too much thermal throttling @80C. If you haven't manually overclocked the card then it isn't overclocked (aside from factory o/c); but using MSI Afterburner or Asus GPU Tweak or EVGA Precision X (my personal preference is MSIA) to set a fan profile can help you with keeping gpu temps lower.

To confirm throttling use the MSI Afterburner overlay to show the GPU core clocks on your card; if you see clock speeds dropping off while you are playing an intensive game when it hits 80C then you'll see the extent of throttling going on.

Okay awesome, thanks for your help!

Okay so I downloaded afterburner and set a fan profile, and now it's hitting around 61C during games whigh is much better, however I was playing on local servers and still getting that screen freeze issue.
Any thoughts as to what this could be?

Also, is my PSU okay to crank up fans speeds and whatnot?

lbPC :

On fan speed+PSU; yes. For the freezing issue; my thoughts are: Driver issue, Game issue, VRAM limit being breached because your settings are too high, possibly server/connection issue.

I would verify if this freeze is repeatable in stress testing and other games. If you have something demanding like Crysis 3, try it on high settings @1080p and see if it is repeatable. Also are you on the latest Nvidia driver? If no then download the newest one, uninstall your current one, install the new one. If yes, download the previous driver, uninstall current, reinstall previous driver. Create a system restore point before installing a graphics driver (to be safe).
