climbing temps xspc rasa kit

post #1 of 40
Thread Starter 
hey,
I've noticed my temps arent as low as they used to be. A few months back, I had an i7 920 @ 4ghz 1.4v with my xspc rasa 750 kit idle @ 35C. Then I switched the 920 for a 950. at 4.4Ghz and 1.4v my idle was 41C. then I accidentally broke one fan than was mounted on the rad, so now I've only got one fan, and the idle went to 42-43C. I also upgraded my power supply, and redid all the cabling, and there are some minor bends and twists in the tubing. Also, the res/pump is mostly filled, but not completely. I tried reseating my cpu block, but my idle temps were at 44-45C. I put the system back to stock, wich is 3.07ghz at 1.2v just to see, and my idle is 40C. I know the temps are in range, but they're higher than they used to be.

Well, the simplest way to get back to cooler temps is to remove more of the flow restrictions and get the second fan back on the RAD.

The RASA water-blocks are real micro-channels. They themselves are good performers but at a cost of increased flow restictions. If you have a pump that is high flow, but lower head pressure, your temps will suffer.

In your setup, a pump that performs like a Porsch (high flow) will not do the job that a V8 Truck has for torque (head pressure).

Idle temps say nothing.

I'd say get your tubing straightened out (literally) and you should see your problem resolve.

Also...yes...get a replacement fan back on there.

rasa isnt THAT flow impeding so that shouldnt be an issue.

also, idles = not important. wha twe want are load temps.

I cant really straighten out the tubes that much since all my cabling is tucked away beside them in the front bay. Maybe I can straighten them out a little. Im just gonna reboot to 4ghz and check out the load temps brb

Idle: 42C
5 mins of 100% load: 71C

Pics of the tubing? It's hard to say how kinked they are and how much it's affecting flow.

Make sure you clean your RAD of dust. Another thing, what TIM did you use? If you used the TIM from the kit, it's rubbish. Would probably want to change that quickly. Your temps should be much lower than that.
