CPU reaching 100c idle windows

[TheBillsProject]

I have been having problems with my custom built PC. The water-cooling doesn’t seem to be cooling my CPU properly as the temps reach 100c idle in windows and 70c in the bios. I’ve had numerous issues with this pc reaching high temps and leaking. I don’t know the problem is exactly but I’m narrowing it down to either pump,loop,bios settings. Any help would be appreciated to try and fix this issue.

Bad mount

[TheBillsProject]

I will check the mounting of the cooler. I just don't like to touch the loop because I don't want it to leak again.

you will not get around touching the loop again, this is either a bad mount or even combined with too little thermal paste.

Agree with above. Either block isn't making good contact or you don't have flow for some reason.

Ok, I will unscrew the block. It's an EK reservoir cooled by 3 corsair fans on a 340 radiator (I think). I will upload a picture. I think the loop might be contaminated as the tubing from the radiator to the reservoir looks white like there is dust on or inside it. I've tried wiping it and nothing so I assume it either something inside the tubing.

Also ingnore the messy cables.

Can you measure water temperature?

I only have bbq meat checker and thats about it.

[TheBillsProject]

Just unscrewed the CPU Block and there is harldy and thermal paste. Hoping this will fix it.

the dirty looking stuff in there can be discoloration of the tubing from the coolant, that what you often get when you use colored coolant and is the reason why many people just use water.

I was thinking of getting clear coolet of amazon. Corsair branded clear coolent. Not sure if it's any good or if it would do the same as the current coolent. I know the picture says red, It's because the clear coolant is out of stock.

It is basically just rebranded mayhems stuff if I remember correctly. It works fine. I have some UV reactive green in mine for about 4-5 months now without issue.

Thanks for the reccomendation.

I have remounted the CPU block and reappied new paste (a good amount at that) The computer still ramps up to 70+ C. I know the tempreture in the uk is quite hot today (30c) But I feel like there is something wrong with the pump,loop or bios settings. Does anyone know what specific settings I should be using in the bios to control the pump etc. In q fan control the water pump doesn't seem to have any settings .I'm would like to know if the pump is actually circulating fresh liquid through the system.

How old is the coolant?

Pastel / solid / non-transparent coolant will breakdown over time, and particles that keeps the color floating will settle, and can clog up CPU / GPU blocks etc.

If that is the case with your set-up, then it is time to perform regular maintenance + cleaning.

Suggested maintenance schedule can vary, but typically every 6 ~ 12 months (e.g. 1 or 2 times a year).

I took this picture last night. What I don't understand is that why has it been fine the last few days up untill yesterday and the day before. 

This is the GPU's block and It is caked with what i'm asuming is the mixture they put inside the loop. Never getting coloured liquid anymore. Hoping clear liquid with the right additives will not cause this mess.

There's your problem.

Your CPU + GPU blocks, are getting clogged; liquid is having a hard time passing through the fin array.

Going to need to clean out your loop.

Yeah, I took everything apart. Wasn't actually that hard, Was worried I would spill the coolant everywhere but caught everything with a container and towels. Will still send it back to get it rebuilt and fully cleaned up with the right stuff. Does clear coolant do the same thing or would it be better? I notice that there is stuff as you said blocking the fins. Would it clump up and clog it as the red coolant does. Just wondering?

Did you not assemble the loop yourself?

Did a custom builder / shop do it for you?

 

Clear coolant is usually distilled water with growth / anti-corossive inhibitors mixed in. That's just what I use, with a few drops of dye.

I purchased the computer a few years ago from Cyberpower. I still have some warranty with them and I have already emailed them. They should rebuild the system for me. I'm no professional with water cooling so I would rather they did it then me putting the wrong stuff in the system or causing more problems than already known.

 

Also thanks for the suggestion, I will ask them to put a different coolant in which hopefully will last a bit longer.

For future purchases you need to understand that opaque coolants are not designed for 1year + use. You WILL need to empty , disassemble, clean and flush the loop at least once a year if u use such coolants.

 

For a less maintenance intense loop u should run just Distilled water + Biocide + Corrosion inhibitor. Doing so will allow u to only do a simple drain and flush every year, no need to disassemble.

Yeah I think brains and common sense went out the window when I purchased the computer. It's a shame because todays standards I could have built a better,cheaper and fast computer with less hassel than the one I got. I will definitely get them to put in a less maintenance intense coolant just as you said. I just need to learn more about watercooling so future events don't happen. 

 

Thanks for the help everyone  Linus forums coming in clutch everytime

I will report back here if anything else happens.
