Hi Guys,

I bought a used PC for my son, but am not happy with the cooling.

Specs are:
Phanteks P300 Case - stock 120mm exhaust fan
i9-9820x CPU
H100i Pro AIO (240mm) - front mounted, i.e. sucking air through the radiator into the case.
GTX1660 Super

The AIO is very noisy when running games, and the GPU temp gets to 83 degrees. It only has 1 exhaust fan at the back of the case.

So I think the hot air from the AIO heats up the case, and then the GPU gets hot?

There is space for 1 more case fan on top.

What would you recommend?
- Add another exhaust fan at the top?
- Ditch the case and get something better to top mount the AIO?
- Ditch the H100i Pro and get a better air cooler? I have always used air cooling in the past.

Thanks,
Greg
 
First thing, move the aio cooler to the top of the case, as there doesn't seem to be a mesh or any real way for air to come in via that case.
With the AIO cooler moved to the top, I would than get some fans to put in the front, hopefully it can suck some cooler air in through those vents on the side.
But 83 degrees for a 1660 super isn't really that much of an issue really, if you see it throttling a lot than it's an issue, but first try moving the aio and adding fans to the front.
nvm just saw that case only has a single fan for the top, you could try putting an exhaust fan there, but I'm not sure if it will help.
 
Can you temporarily put a thermometer in the case to see the case temp? That should tell you if you need to do something about the case airflow or maybe repaste the gpu.
 
Thanks, I'll measure the case temp.

I have a 140mm fan that I can test as an extra exhaust at the top.

Main issue is that the AIO fans are really loud.

Probably dusty, take them out give them a good clean, depending on age the bearings could be going as well.

Noise is also amplified by the crappy case. Fans sucking air through the rad.. through small front panel bottom and top intake gap only.

Try remove the front panel temporarily and see if its better. If it is, get a new case :P
 
Would definitely check into how easy it is to repaste the GTX1660. Agree to move the AIO to the top of the case as well. Cable management also goes a long way to improve airflow inside the chassis so try and tidy up some of the loose cables hanging around the fans.

That case reminds me of the crappy evetech cases. Little to no airflow from the front so the fans could be spinning at 100% to get the temps down. I would suggest something like the Corsair 3000d and moving the rad to the top.

A lot of the "older" cases were like that with the vents on the side and top, it was probably only around 2017/2018 when mesh became more popular. Though some coolermaster cases did seem to have holes on the front sooner.
 
Rad on top, pushing outwards. Additional front intakes. Sorted.
 
Thanks, I did clean the radiator and fans - full case clean.

Could change the case, but I think when the fans spin up they will still be very noisy.

Even if set to "quiet" as soon as the CPU utilization goes up, the fans spin up and get noisy.

It seems like the fans are just generally noisy on the H100i Pro (ML120 fans), so I could consider something like the Arctic P12 Max fans.
 
Yeah get a new case. There are excellent options available for ~R1k from Wootware.
 
In the good old days you got these silicone padding for your fans, where it could actually dampen down the noise. You can always put in some padding to quiet it down. Ive

What is your PSU? Can it handle that load? A PSU running a heavy load can add a lot more heat.

"The inefficient power utilization by weak or small power supplies also causes excessive heat. This inefficiency and power waste causes your device to overheat, leading to long-term damage to your hardware and even the risk of fire safety hazards."
 
As has already been suggested, try running it without the front cover. That thing is highly restrictive. This will help to narrow down where the main problem lies.
