I recently bought one of overclockers "Configure your own pc" PC's. I have had it for 2 days and noticed it gets really hot, so I downloaded core temp to see how hot it was. I also downloaded prime95 to run a test. The idle temp of my cpu was around 45-49c and when I loaded up prime it shot up to 85c so I turned it off as I didnt want to break the cpu. I have a h50 cooler for it. I dont think this should be normal, but then again im not a PC wiz. Can anyone tell me if this is normal for my cpu please. I have a GTX580 inside this pc, and that never goes over 59C even in games.

I dont know, OC built it for me. I'm not confident enough to take it apart, as pc's are not my area of expertise. Also I dont have any spare thermal paste as they built it. Is the cooler meant to make watery sounds? Just asking cause it doesnt.
 
I don't think so, I don't own a water cooler myself and so I couldn't tell you for sure. You should contact OcUK and see what they say about it. It's possible, yet unlikely, they did not put the cooler on correctly
 
I did contact them actually, this is what they said:

I would recommend checking where the pump is actually plugged into on the motherboard, it sounds like it needs putting onto a 3 pin fan header, you should see the wire coming from the h50 pump on top of the cpu and be able to trace where it is plugged into, the pc will not overheat and blow up as they have safety features which automatically turn it off if there are any serious errors

I'm not actually sure what he means.
 
Ok. Unfortunately this is going to require you to open the case and plug something in, or just have a look ;) Trust me. Its easy, built my first PC when I turned 13.


Find the screws that are holding the side of the case in place, unscrew them and lift off the side plate.

Find the pump. It will look like a cylinder and have two tubes coming from it leading to a radiator and a fan usually at the back of the case.

On the pump, there will be a wire with a plastic plug on the end. The plug will have 3 pins.

Now you need to find a little socket on the motherboard which is your fan header. It will have place for 3 pins. Once you find it, it should have a number next to labeled CHASSIS_FAN X/ SYS_FAN X (Where X is the socket number) plug the pump in.

Put the side plate back on, and turn on your computer. You now need to go into the BIOS and change the fan settings so that it is always on 100%. Make sure you only change the fan that is the same as the number you saw. Exit and save your changes.

Boot into Windows, open Core Temp and check you temperatures :)

Well I think I changed the speeds there was a chassis fan and cpu fan option. There was no -/+ to change the RPM, but I did change the Q-fan controls to turbo. Is this what you meant? I still see no difference though.
 
The h50 pump needs to be connected to a fan header that supplies a constant voltage, or to the psu via a 3 pin fan - molex adapter. An ideal header, particularly on asus boards is the pwr fan header, this supplies a constant voltage, unlike the case fan/cpu headers which can be speed controlled unless you disable control in bios.
 
Right I must have done something wrong when I changed the fan speed cause it said windows cant start something is wrong with the system, or something along those lines. Should I be worried about that? I changed it all back the way it was and I can get into windows now. But still high temps :(
 
Yes one part is in the CPU and the other is connect to the SYS fan.

But one other question I havn't F'd up this pc by screwing up the fan speeds have I? Cause windows did say it wouldnt start after I did it, but it works now.
 
What part is in where? You need to make sure that the actual fan on the radiator is in CPU_FAN and the pump is in SYS_FAN.

I don't think that changing the fan speeds would muck Windows up.

What motherboard do you have? I'll download the manual and have a look through the BIOS, see if I can walk you through it.

First off, nice board ;) But now down to business.

When you first go into the BIOS, you should go to Power, then Hardware Monitor. Go down to Chassis Fan 1/2 Speed (depending on what header the pump is in) and press + to raise to 100%. The press F10 to save your changes and exit the BIOS.

Is this what you have been doing? If so, then I am completely stumped and I really can't think what my might be causing your problem. Otherwise, open Core Temp!!
 
There is no fan speed option to set it to 100%, just the actual speed it runs at. There is only the option to turn on Q-fan controls.
 
Ok then raise the speed it runs at to as high as possible. You cannot damage anything because the motherboard can only supply so much power.
 
Does the motherboard have a fan connector labeled as PWR fan? If so id connect the pump to this.
 
Yep, an adapter would do as well. But on asus boards the PWR fan header runs any fan connected to it at 100% all the time, therefore making it ideal for the h50 pump. When connected to a sys fan header, you have to be careful that you dont have speed control enabled as this can lead to the pump not receiving sufficient power.
