Corsair H60 & i9-9900K temperature help

[chabert]

Hey guys.

 

It seems I am having trouble with the cooling of my CPU, which is done by Corsair H60.

The idle temperature of my CPU is 60-70 degrees Celsius. If I start to play CSGO the temperature of my CPU jumps to 90-115 degrees Celsius instantly and it doesn't go down. It stays at that temperature.

 

After opening the PC, I have observed that one of pipes of the Corsair is extremely hot but the other pipe is regular living room temperature.

 

Does anyone here have any suggestions for solving this problem? Any idea what is setup wrong? Or is it possible the cooling fan is faulty and should be replaced?

 

The PC is built by me.

 

Hardware setup:

Corsair fan is plugged in to CPU_fan on the motherboard

Pump is plugged in to to Fan_opt w/pump

See picture https://www.asrock.com/mb/features/Z390%20Phantom%20Gaming-ITXac.jpg details

 

BIOS setup:

CPU is the temperature source

Sat to water pump with DC full speed

 

PC specs:

CPU: Intel Core i9-9900K Coffee Lake S

Cooling: Corsair Hydro H60

PSU: Corsair SFX series SF750

RAM: Corsair Vengeance LPX DDR4-3200 16 GB

Motherboard: ASRock Z390 Phantom GAMING-ITX

Harddrive: Samsung 970 EVO Plus SSD M.2 2280

GPU: MSI GeForce RTX 2070 VENTUS 8G

 

Thanks in advance

It appears you have a flow problem. A 120mm radiator can only take about 1C off the coolant temp on a pass, so the tubes should be within the same 1C of each other - an imperceptible difference. This usually occurs when you have some type of blockage.

 

What does the BIOS report as the H60 pump speed? It should be 4000-4400 rpm. I am assuming your ASRock lets you set independent controls for CPU and OPT. Not all boards do. If the pump speed is low, that is something to investigate.

 

However, since I imagine this is a new development and the idle temp suggests your coolant is floating in the 50-60C range, you need to Contact Corsair through the support ticket system to start the RPM process or start looking at a new cooler. It would be nice to have a double pane 240 or 280mm radiator for a 9900K, but I don't know your space limitations.
