Question Corsair H100i SE on Ryzen 3600x stock strange temps

[christoffe93]

Hi guys as the title says I've got a corsair h100i and the temps seems abit high considering its a watercooler. At idle the water temp is 31c and the CPU temps is bouncing between 41c and 45c but its very erratic hitting 51c now n then i'm also using thermal grizzly conductonaut so i was expecting much cooler temps at idle i also have the pump and fans set to moderate and the CPU undervolted to 1.18125. I've reapplied the waterblock a few times and checked to see if i applied to much paste to the CPU but all is good. I know those temps are ok but not when you've payed over £100 for a cooler that supposed to be superior to the factory cooler.

What is the temperature in the room where the PC is used. So far nothing seems out of normal temp wise even with a h100i.

Conductonaut isn't paste?

You can't stop low load temperature spikes. They are going to happen. 7820X I have here sometimes sees spikes into the 50s(rarely does it touch 60C), in a 24C ambient room, direct die mounted with an Eisbaer 360mm AIO, getting air direct from the room, using TG Conductonaut.

Is the loop being fed room ambient air, or case ambient air. It does make a difference.

There's other factors too - like power plan, silicon lottery, bios voltage curve, etc, but if you bought that solely because of low load thermals, then that's an easy way to waste money.
Full load thermals or overheating during game loads is what a cpu cooler purchase should be based around. It's easier, and there are fewer variables at play.

Im not to sure but it is hot in here im sweating as we speak as the uk is going through a heatwave it was 32c earlir but its 25c now and the temps are still weird. The coolant temp doesn't seem to be moving and the fans aren't really doing much, i've just had 1 hour on black ops cold war everything maxed out n the temps got upto 57c but the coolant stayed the same i also have the cooler directly mounted to the fans on the front of my case the rgb ones that come with the phanteks g360a i think they are called sk120. How is that possible? The only possible thing that's come to mind is ambient temp as i do find it strange how the waster is already 31c when i turn the system on but surely the rooms cant be 31c, right? shouldnt the coolant and the cpu temp be a few degrees apart.

If you are getting a max temperature of 57c during gaming you are doing a heck of a lot better than the stock wraith prism cooler. I don't really see how you have a problem here.

I was just expecting more from the idle temps as those temps will increase if i overclock the CPU there's nothing worse than browsing the web with fans blowing their head off i already have the cpu undervolted by alot at stock setting to get 57c if i were to increas the voltage and oc it i recon i will be pushing mid 60s at idle. The whole point of buying liquid was to run it at low noise and possibly zero fan rpm at low loads but its getting similar temps at idle as a standard cooler and this is on liquid metal compared to the standard cooler that was on artic mx-3. Considering this cooler cost £130 new and the paste is for extreme overclocking the temps are seem Sh=t. I feel like a was sold a golden goose and got a pigeon instead. I've used liquid metal in the past on my old r9 280x and the temps dropped around 16-18c so the past does work miracles which makes me wonder what sort of temps this £130 scrap would achieve on normal artic paste or noctua. I'm now running the idea64 stress test so CPU,FPU, cache and system memory and its so far hitting 83c after less than 1 minute of running.

The temp can never be lower then the ambient room temps. Example, my room is 22C ambient. My Cpu has a much better cooler then you and I idle at 32c, under load 60c, all pretty normal.

How much cooler do you want it to be ? 10c over ambient is quite normal and so are "erratic" temps because true idle is hard to achieve as Windows are always doing something in the background.

Perhaps your cooler would do better using higher static pressure fans?

Maybe its all this hot weather we are having as its been 37c the last 2 days where i live so prob not the best time to measure its potential under normal conditions. What threw me off was the lack of thermal transfer between the CPU and the AIO you'd expect to see the temp of the coolant and the CPU relatively similar temps. If i do a stress test with idea 64 it will shoot straight upto 79-80c while the coolant will barely move. Its almost like there's not much heat transfer happening. I would expect the water and rad to get warm and then the fans draw it away but the CPU gets warm and the coolant stays between 31c-33c in all conditions. I just dont get how a h100i is unable to beat the standard cooler even the thermal paste use on the standard cooler was much worse "cooler master E1 IC essential" vs "thermal grizzly conducternaut". I don't even have the benefits of using the AIO for lack of sound as its already high enough temp to cause noise issues if i was to OC it so im literally back to square one again and £130 out of pocket.

I remember doing a prime95 stress test with the stock wraith cooler and it shot up to around 95c

Amount of heat and temperature raise is always much, much faster in CPU/GPU itself and heat transfer from cores to cooler base is a weak link no matter what paste. Heat absorption from cooler primary absorber is also delayed with every next step with even further delays and temperature reduction. In case of liquid coolers mass that has to absorb heat is much higher than in air coolers so it takes longer to saturate. By the time all that heat transfer is enacted, in most cases CPU temps are already falling or fell to lower levels and water not being best heat transfer media didn't have time to heat up, (liquid metal would do it much faster and more efficient). Some types of nuclear reactors use molten lead for that reason.
So, to start with CPU cores which are measured in Microns, heat has to be transferred to thousands times larger cooler core and from that to water many times larger mass which has to transfer to radiator and than to air that is more of a insulator than heat transfer media.
As for price of AIO coolers, most of it goes to gimmicks s it's not a final measure of it's efficiency.
