HD 7990 Xfire

keikeimok · 11 Sep 2013 at 11:29

I am currently running 2 7990 in a loop. I think my loop can't handle the heat I use for mining. (1 x 360 (push) and 1 x 120( push-pull) EK thick Rad.)

In this weather, it slowly climbs to 71C . dun wanna push it no more.

What exactly is the question? 71 degrees isn't really that bad, bearing in mind that temperatures will drop soon anyway... especially for a 7990.

71C is fine.. nothing to worry about.

Under water? Too high

Stick a second 360 in there if you can

Well it is higher than usual watercooled ones, but he is using all 4 cores on max all the time for mining and 71C is perfectly fine for this GPUs.

Sounds ok to me. Warm room about all

Running 1 x 7990 for mining with a 360 and 240 setup and get around 60 degrees.

Nice setup btw

If a water cooler GPU runs over 60c its simply too hot for my likening, poor CPU is on same loop

I think so too especially when I read about the Max temp the pump and the tube could stand of is around 60C.

Dun wanna melt those tubes and end up in disaster. LOL

Yeah, I think I would consider replacing that 120 which is lying outside the case to a 360 one.
I am currently using CM HAF X. which I think there are not enough space for more rads inside.

Need to know what the room is like, is there good airflow in the room? Whats the ambient temperature in there when the gpu's are at 71°C?

Sometimes if you have kit that is constantly loaded 24/7 @ 100% in a room with no aircon or poor airflow then it doesn't matter if you add more radiators you are going to get high temps.

oh yeah, I see.
Those computers are in my study room, no aircon, ambient temp would probably much depends on the seasons and climate.. that's why I can't run them 24/7 lately...
I hope winter is kicking in soon... LOL

Do you suggest I wait and see for the 360 rad upgrade?
