I bought my pc used. And have always kinda noticed my cpu aio coolent (corsair h100i) hitting 60c when playing games. I've ignored it as I haven't played games much till recently. But not taking a closer look. My rear fan has some beefier blades and the two front ones are way more airflow. It seems backwards to me since the front of the case doesn't have a lot of opening and the psu bay is right behind the bottom fan. Should I get a noctua airflow for the back and static pressures for the front?
Edit: Forgot to mention my room's ambient temp is 21c
Also the aio itself is only a year old. And pump speed when gaming is around 2400 rpm
Clean your PC it’s filthy.
No you don’t need to worry about new fans 60c is normal. Now if you where at 80+ for long periods then maybe a new cooler would be worth it. Also that case has terrible airflow bigger/newer/stronger fans won’t help.
It’s likely the aio is nearing EOL as well they only really last 3-5 years and slowly loose performance over time.
But 60c for the coolent (not the cpu itself) puts the aio into failsafe. 60c is also the max any coolent should be hitting
And yah the dust is starting to get bad. Just moved it into a new room that was unused for several months and collected dust. But the camera flash makes it look worse than it is in some spots. Admittedly the fans themselves are pretty dusty
And the aio is only a year old
Overall a solid build. However, dust is the big culprit there, but the other factor is the front of the case. Appreciating that I only have your pictures to go by, the front looks terrible for intaking air. Those holes are so small plus air has to make a 90 degree turn before it gets drawn by the fans into your case. It's the equivalent of trying to breathe through your nose while one of your nostrils is stuffy - sure it'll work, but it could be better.
Regularly cleaning your PC when it gets dusty will fix a lot of problems with airflow. For now, your AIO is doing a great job keeping the CPU cool.
If temperature eventually does become a problem, the next step is to swap your case out with something that has much less restrictions on the front. There's lots of cases out there to pick from, but a solid popular one is the Corsair 4000D, to give you a reference point of what to look for.
EDIT:
Just saw you also mentioned your thoughts on upgrading your fans that I thought I'd respond to. I think you're fine for now if you just clean your PC and make sure that air can get through those holes. If you notice temperatures get really bad to the more critical components, I recommend case swap to introduce more airflow. Your money's better spent there.
