First water build - questions about temperatures...

post #1 of 9
Thread Starter 
Here are the components that I am using, I figured some experienced people on the boards could help me figure out whats up with my seemingly high idle temps of 39-45 C

1. Alphacool NexXxoS XP Bold Highflow Socket 1366 Waterblock
2. Swiftech MCP350â„¢ 12 VDC Pump
3. Bitspower Premium G1/4" "Stubby" High Flow 3/8" Fitting
4. PrimoFlex Pro LRT UV Green Tubing -3/8in. ID X 5/8in. OD
5. Arctic Silver Matrixâ„¢ Thermal Compound
6. Black Ice GT Stealth 240 Radiator
7. XSPC 5.25" Bay Reservoir
8. 2X Yate Loon 120 x 38mm Low Speed Silent Case Fan - D12SL-12D (PUSH for radiator)

I am using a Corsair HAF X with the big top 200mm fan and 230mm front fan running...however not the rear 140mm running. Also, I have only attempted one application of the thermal paste and might have to do it again to see if that makes a difference. Also, I have used roughly 5 feet of tubing.

Thank you all so much. I have read and read tons of build logs and have admired many user's work here and have finally build my own rig! I don't think my temperatures are BAD just that they could be lowered for sure.

Your fans aren't powerful enough for the rad even though they're 38mm thick. The Stealth rads have a 30 fpi and need fast fans for best effect. As far as I can tell the fans you have spin at a max of 1350rpm.

Edit: You could also get a big improvement by switching to a decent thermal paste.

A paste that is readily available, cheap, easy to use and gives good results is Arctic Cooling MX2.

thanks to all for the replies. I installed two slim fans but with much higher RPM than the first two and now I'm at 30-34 C. One of the cores is displaying 38...is that normal for one to be a lot hotter than the other three?

It is. You really need to get load temps to get an idea of how effective the loop is.
