Weird temps.. - Page 2

post #11 of 13
While the radiator fans could absolutely stand some improvement, I sincerely doubt that he is running 20 degrees Celsius too hot because his fans are a bit weak....

The first thing that comes to mind for me is: the 90deg fitting immediately from the pump outlet (leading to another 90deg), and it's a rather sharp angled 90, not like the Bitspower ones that are actually completely smoothly-curved inside. The issue is that 90's can cause cavitation in the pump sometimes.

I don't know if D5's are more prone to this or not, because I have my MCP35X (which is sometimes swapped for an MCP35X2) connected directly to one of my reservoirs (the bay res) via BP 90deg rotary adapter and BP male-male rotary coupler fittings, so it's a 90deg angle into the pump; it's never caused a single issue for me.

It may also be that it's different when on the outlet than on the inlet.

akiles333 - I'm afraid the solution is to disassemble everything, flush your rads (this is a must for any new rad), I'd have a look inside the blocks as well. After that I'd recommend assembling the loop on a bench (mobo box will do) where it will be much easier to test and check the stuff. After you are happy with the setup you can move to the case and enjoy your rig. LC is for patient people only in my opinion.

Some other thoughts: the guy in your link is using 4 AP-15, if they run full speed they can make noticeable difference compared to your fans (especially that you need full cooling power of 2 240 to cool 3 blocks). You may try putting some beast fans first to see how it works, if you really don't want to re-build the loop (which I would do anyway). Try borrowing some AP-31 for the test tongue.gif

i'm gonna try with new fans first. But is 52 as a max after 5 mins with furmark bad for only 2 240 rads on the gpu's?
