Taking off side panel ruins airflow, it will be hotter.

So you’re also saying you only have one fan in the entire PC other than the radiator fans? You ideally need one intake on the front and one exhaust on the back, at a minimum. 

Have you verified your pump is working yet?

Yeah, I have a CPU fan but for some reason it doesn't seem to work. 

I'm not too sure how to check whether the pump is working correctly. I can hear the water flowing when I turn my computer on if that means anything?

I guess that’s a good indication. How do you have a CPU fan and a water cooler that doesn’t make sense. show us some pics of your PC inside?

I mean the fan on the case, I don't have a CPU fan dedicated to the CPU.

To be honest @Ollie630‍ it just sounds like there's not enough airflow. Your radiator won't get cool enough either if the ambient temperature is high in the case, because it blows air inside the case onto the radiator typically with AIOs.

Get some new case fans, if your case supports it try getting 2 on the front to intake, one (or 2 if u can) on back to exhaust then you should be in a better situation. No amount of thermal paste will sort out the problem of the inside of the case being too hot.

Alright, I'll take a look at some new fans and see whether my case will support any more.

Thanks

Add me on discord if you need more help. Will assist with what fans you need for your case.

Water flowing is indeed a good indication you have a working pump. You already checked radiator fans, right, and that it's not clogged? Coolant alone won't cool your CPU - you need a working heat exchanger (your radiator). This needs access to good airflow. 

It's also possible there's air in your plumbing. This will decrease the efficiency of your cooling unit. You could theoretically bleed this out but it's going to be a pain, and there's no guarantee it's even there. 

It might be worth contacting the manufacturer of your cooling unit.

Agree, this is very likely the key problem (more likely than my theory about air).

Your cooling system works by pumping coolant, which receives heat from your CPU. The coolant pumps through a heat exchanger (radiator) and heat is dumped to ambient air flow. The rate of heat exchange is dependent on the different in temperature; the greater the difference, the more efficient. If your ambient air in the case is hot, this heat exchanger will perform poorly.

I'm going to try and connect the extra fan on the case tomorrow to see if that makes a different, but then if it doesn't I'll take a look at some more fans and then possibly a new cooling system. Would you say that's the best thing to do? @"livkx"‍

And @Faustie‍ I'll get in contact with the company tomorrow when they're open again to see what they say about it

Good plan fella, try get as much airflow as you can and make sure the one on the back is exhausting not intaking!

I agree that having an extra case fan will help temperatures massively, but two intakes aren't necessary at all. Once you have one intake and one exhaust, there's a case of diminishing returns.

A second intake can be helpful, but it's not needed, and definitely won't be the solution to overheating if having one intake and one exhaust doesn't solve it.

Exhaust is the most important if you only have one case fan, so for now, I'd ensure that the one case fan is set as a rear exhaust.

I don't think it's within the realm of possibility that Ollie has a badly binned CPU to the point that it overheats at stock with water cooling. It would be an extremely rare case, and he would be able to contact Intel if that were the case.

I have the same CPU and it rarely goes above 50 degrees and that's in an NZXT H440 case and being cooled by a Corsair H105.




I might have missed it in the post but what heatsink and case do you have?

[Ollie630]

I contacted my local computer repair shop and they told me to tighten the water cooler which seemed to help a lot as I'm currently running Garry's Mod and it hasn't crashed. However, if it continues to crash, they told me to go to their store and they'll properly diagnose/fix it for me.

Thank you to everyone that has helped!

Could i ask, Do you have the latest windows update? I've seen a few posts on various tech forums that it's causing CPU temp errors

[Soviethooves]

It could be your cooling system is just not working. Have you tested that or was that already mentioned?

[I Too Have An Uncle]

What voltage is the 4790K running on. Some people have had the voltage randomly turn up in the BIOS. Also is your BIOS up to date?

I'm pretty sure I do, but I don't think that it has caused the crashing as my CPU was overheating before I downloaded it.
