Hello forum,

Specs:

CASE: NZXT S340

MOBO: MSI Z170A M5 Gaming

CPU: intel i7-6700K

CPU FAN: Corsair h100i v2

GPU: MSI GTx 1070 Gaming X

RAM: G.Skill Ripjaws 3200 mhz 2 x 8 GB

PSU: Corsair CX650M


I recently bought these components and built my pc lsat night. Everything seemed to be working fine, but at first boot and going into the BIOS, I noticed the CPU temp started at 50 degrees Celsius and continued to steadily increase to 100 degrees Celsius.

I proceded to install windows and my drivers to see if that would do the trick, still nothing.

I went back into the BIOS and checked the system board to see what was connected and disconnected. The BIOS stated that the CPU_FAN1 & CPU_FAN2 were both disconnected. However, I have my fans connected to CPU_FAN1. I feel like this is the issue but am unsure.

I made sure the backplate for the CPU was tightened securely and that the CORSAIR h100i v2 was placed securely on the CPU but still nothing. I put a decent amount of THERMAL PASTE, which is too much? Also, the thermal paste I applied was used in my brothers build a month ago, is that alright?


So, how do I fix this issue with my water cooler?

Thanks for your help in advance everyone.






UPDATE: I tried moving the fan controller cord ( initally plugged into CPU_FAN1) into the other CPU headers and SYS headers, still nothing. They aren't being detected in the BIOS.

I am using the Board explorer on the MSI click BIOS 5.

Depending on where you bought the unit. That should be your first port of call and an RMA should or could be raised with them. Here in Australia the retailer is responsible for the first 12 months.
How unlucky however it can happen and Corsair are good with RMA.
Follow this guide: http://www.corsair.com/en/blog/2013/february/how-to-install-the-hydro-series-h100i-cpu-cooler

The unit comes with thermal material already applied to the CPU cooling unit and applying too much Thermal Paste is not good as AIR can get trapped within the paste and not provide a proper thermal transfer. TIM should be applied about the size of a small Pea and is there to fill just the tiniest of voids. You may have to remove the unit clean up the existing paste with Isopropyl alcohol 95% and re apply with AS5 or MX4 which have excellent thermal conductivity.

You may have not hooked up your H100i correctly and 100C core temperature will kill your CPU if you continue.
Check your cabling and connections to the MB and that the 24pin JPWR-1 and 8pin JPWR-2 are secure. Refer to page 26 in your MB manual for CPU_FAN1 and other fan headers and connections.

If installed correctly you should feel the pump buzzing slightly and the tubes from the unit will get warm.
Also you may have tightened the CPU hold down bracket too tight and should only be finger tight.

Temperatures at idle should be no more than 10-15C above your ambient room temperature.

ive tried all of this and still nothing :(


I did ahve a bit too much thermal paste but i cleaned it up and applied a pea size amount. Next, I checked my cable but they are plugged in properly but the cpu fan header isnt being recognized, but I am confused because if it wasn't able to how can it read me the temperature?


UPDATE: The temp has now dropped and is a stable 65 Celsius @ 6% load. This is much better but nowhere near where it should be. I tried the corsair link software but it isn't detecting my pump, only the CPU core temps. I have the USB plugged into the pump and into the JUSB slot on the mobo.

So to clarify: There's a 3-pin fan-type connector that comes out of the H100i's pump, and that should be connected to your CPU1 connector on your motherboard. This is to power the pump, which sounds to me like is what's not working (the pump). The two fans on the radiator actually connect to the pump, not your mobo.

Even without the fans running, I wouldn't expect temps to rocket up like this. The important thing with these coolers is that the pump is running so it can keep cycling cooler liquid through, on top of your CPU, so the hot liquid gets away from the CPU.

I've done this marko55! The fans are connected to the pump and the pump 3 headed pin is int he CPU_FAN1 header!! The usb is plugged into the pump and the other end is int he USB1 port on the mobo. I tried placing it on the JFP2 pin slot on the mobo and the pumps turned on!


However, the head of the usb connector plugged into the pump began to melt!!!!!!! I shut it down immediately!
