Adding 980x to loop

post #1 of 11
Thread Starter 
I currently have 2 GTX 580s on my Custom Loop running at 1.1v and 902Mhz.
My temps after about 60 minutes at load is 45c.

If I add a 980x with HT disabled and ~1.4v @ 4500Mhz what temp increase can I expect?

They don't actually produce more heat then any other 32nm process CPU

Should be fine at 4.5 w/HT

His 920 is 45nm

Still, I don't think you'd see a huge difference in temps. You still want to keep an eye out, though.

I have 2 dual 120mm rads, but my 920 currently runs on an h70 at around 60c in prime95 maximum heat settings.

I am going to attempt to use the h70, but if the temps get over 75c I want to switch it into my loop.

so 2xdual120mm swiftech rads, with CPX pro pump, 1 rad has 2 120mm fans and 1 has a single 200mm fan.

Edit: also currently with the 580s at load I am only getting ~40c because my PC room is much cooler than where I installed the system.

You will see about 5-10c higher idle temps and 20c higher load when your system is full load (cpu+gpu).

Give or take. Depends on which brand your radiators are (not size, brand).

The GPUs' load is that low because GPUs don't give off alot of wattage in comparison to a cpu. I thought you already had your i7 in your loop...you're going to need better fans/rad than that if you're going to put a 980x in there. I'd suggest a thick triple or quad with some 38mm fans

They have several models.

If these are the simple slim radiators, they won't be enough to clear the heat.

As said above, its better to use a good thick radiator.
