Meusli Posted November 25, 2014 Share Posted November 25, 2014 I have built a new rig today and installed the H105 as my CPU cooler on my new 4790k, the idle temperature though is sitting at around 50oC. This is only a load of approximately 20-30% and I feel this is a bit high before I begin to throw stuff at it. I have not been able to get it to move down in temperature no matter what I try. The motherboard I have has a special pin for water coolers on which it is attached the light on the cooler is lit and I have the fan seed set to high to give it extra power it needs and I have even reapplied thermal paste to the CPU all to no avail. Please help me as I want to play games. :/ Link to comment Share on other sites More sharing options...
LangZone Posted November 25, 2014 Share Posted November 25, 2014 That is too high. Go into the bios and set the header that the pump is plugged into to "100%" or "Full" speed and let us know what the rpm is. You could also try reseating it with new TIM.

Meusli Posted November 25, 2014 Author Share Posted November 25, 2014 Thanks for the reply. :) The cooler it is plugged into a Gigabyte GS-Z97x-UD3H-BK CPU_OPT header and I already have it at at full speed. I have already replaced the thermal paste once as well. I just ran Prime95 and one of the cores reached 91oC. :/ Link to comment Share on other sites More sharing options...
Meusli Posted November 25, 2014 Author Share Posted November 25, 2014 Should there be a sound coming from the pump block? I can only hear a faint electrical buzz. Also how to I tell what the RPM is? OK I downloaded a program called Speed Fan and it is telling me the following; Fan 1: 0 RPM Fan 2: 1839 RPM Fan 3: 0 RPM Fan 4: 1493 RPM Fan 5: 1464 RPM I take it Fan 2 is the pump and the other two are the fans for the radiator cooler.

Corsair Employee Corsair Dustin Posted November 25, 2014 Corsair Employee Share Posted November 25, 2014 The pump block should be basically inaudible. Also, check the RPMs in BIOS. Link to comment Share on other sites More sharing options...
Meusli Posted November 26, 2014 Author Share Posted November 26, 2014 The pump block should be basically inaudible. Also, check the RPMs in BIOS. I have checked the Bios and it is reporting the same thing. one thing I have noticed though is the two fans included do not always start up if the are plugged into the system fan power, I have to restart the computer several timers to get them to "catch" or set them to full and then back to normal.

Corsair Employee Corsair Dustin Posted November 26, 2014 Corsair Employee Share Posted November 26, 2014 That almost sounds like an issue with your motherboard headers delivering adequate power. Link to comment Share on other sites More sharing options...
Meusli Posted November 26, 2014 Author Share Posted November 26, 2014 Power supply not enough (750w) or faulty motherboard do you think? I have turned the heatsink around so the pipes are less bent and that is helping somewhat but its not as low temperatures as some people are reporting still.

Corsair Employee Corsair Dustin Posted December 2, 2014 Corsair Employee Share Posted December 2, 2014 Possibly a faulty motherboard; 750W is fine for most builds (though I don't know exactly what you're running). Try plugging the pump into a different motherboard header and disable the fan control for that header in BIOS. Link to comment Share on other sites More sharing options...
