[SOLVED] problem with the AIO installation, CPU overheating

[AlaaLU]

I have a problem with my water cooler
my new cpu reaches 95c once I start rendering and clocks at 2.3 and it's a ryzen 9 3950x

the person who assembled the pc for me was not very experienced and likely he did something wrong

so I asked here yesterday about the issue and people answer the following?
1.pump is not running on the water cooler (the manuals for the cooler and motherboard will tell me how to connect it)
2.bad AIO installation, cables not plugged in the right place
3. I need to remove the plastic layer that protects the thermal paste if it's still there.

I don't have someone experienced here to look at it so I need to do it myself and I know nothing about hardware, I checked the manuals and have no idea where to start
and I don't know if I need to buy a thermal paste before starting or not

can someone help me in more detail on what to do?

hi, if u want to remove cpu cooler (any) from cpu, then u will need thermal paste
as far as water cooling goes (no matter if aio or custom loop)
pump will need to go full speed, its quiet (no noise), it just moves water around your loop (usual rpm about 5000), and u want move water fast from cpu to radiator
fans moves air from radiator to surrounding area (front intake, back or top as exhaust)
increasing fans speed will move air faster (thus reducing temperature on radiator)

What is the make/model of your case and what is the fan arrangement?
Where is the radiator mounted?

What is your temperature at idle?
I would expect 10-15c. over ambient.

1. Are the case fans running in the proper orientation?
You likely want the front fans to draw in fresh air.
Dangle a tissue in front of a fan to see which way air is flowing.

2. Normal aio installation would put the radiator at the top of the case with air flowing out.
Mounting the radiator in front, drawing air in is also reasonable.
There are pros and cons each way.

3. A possible error is that the pump is not level on the cpu.
If you remount, tighten down the screws a bit at a time on a criss cross rotation.
If done one at a time, you will not make good contact.

4. If you decide to remount the pump, yes, you need to replace the paste.
Most any name brand will do. AS5 for example.
First warm up the cpu before shutting down. That lets you unstick the pump easily.
Clean off the old paste from the cpu and pump using alcohol.
70% to 91%, the more pure the better.
Use a paper coffee filter to do the cleaning. It is lint free.

5. One rookie error is to not remove a protective mylar cover on the pump before installing.

thank you, i'll have to buy the thermal paste first before doing anything

My case is Cooler Master TD500 , 3 front fans (one back still didn't buy it)
Cooling: Cooler Master MasterLiquid ML240R RGB
the case is always cool even when i'm rendering and the CPU is at 95c

the CPU temp when i'm not rendering is around 70c

just a tip, moving gpu to first long pcie slot which is closest to cpu will slightly improve gpu performance

Great! will try that, thank you
