Push/pull on RS240 rad

post #1 of 11
Thread Starter 
Hi all

I have just installed my first loop and everything went well except for the temps. I am running an I7-930 at 4.01ghz and temps are at 72c, which seem a bit on the high side.

Anyway, I have the fans located at the top of the case pulling air through the rad and out the top. Would it be better temp wise to switch round the rad & fans so air is being pushed through the rad and out of the case?

Reseat the cpu block. Maybe it wasn't seated right.

I would do a push method if you can't do a pp method

Those temps aren't too off for using an RS240. i7 930's get hot, real hot, so I wouldn't be surprised to see 65-70C temps, especially if you're using a lot of voltage. Using push + pull would lower temps a few degrees, and if you didn't tighten the second nut on each corner of the RASA waterblock, contact may not be optimal.

Whats your voltage on CPU and speed on fans as well as ambient temps? These play a huge factor on your temps.

My 950 at 4ghz is stable 60c w/ prime95 running for few hrs w/ a similar water block. Idles at 30-40c. Yeah like what they said reseat the water block. Oh and make sure the pump is ON.

Is it stable under load? If so, what's the problem?

Your 950 probably requires less voltage than his to hit 4 GHz. Voltage is a huge factor in how much power is going to be drawn for the CPU. Add this variable in with ambient temp differences, normal variations in mounts, and variations of how accurate temperature sensors are, and you easily get that 10C difference.

And obviously his pump would be on, otherwise he'd almost instantly be overheating and his computer would be shutting down. It's impossible to run a stress test and stabilize at 72C if your pump isn't on.

I forgot to plug my pump in when I first got my water loop and hell it was 85c at idle it didnt shut down. and i thought i had seated the block wrong.
