Cooling noise/High temps when gaming

[SpyderTracks]

Ah so you're saying with the Cappelix fan change from top to bottom, the rear fan exhaust should be enough?

Yes

 

[Sceers]

Yes

I will try make the fan change this weekend. I might know someone who can help me, so I'll keep you guys posted. Thanks for the advice

Mesh alone isn't effective at pushing air through a case. It ideally needs a good exhaust fan on the rear of the case, and exhaust fans at the top (which is often where the CPU/AIO coolers are placed).

From what I've seen, whoever built your PC installed the pump and radiator correctly, but they installed the fans on top of the radiator instead of underneath it.

In terms of re-installing the fans, you'd only need to unscrew the fans from the top and install them in the correct position. You wouldn't have to remove the pump for this. You can see the video + images to show which is the correct placement and direction for the fans. I'd also be gentle/careful doing this to make sure you don't accidentally disconnect any cables (if possible, pay attention to where the cables are before doing this).

If you're still not comfortable doing it yourself, I would get PCSpecialist do to it as they should have done it correctly in the first place.

Watch the first minute of this video for how to install the fans correctly:

When changing the fans from the top to the bottom, are the way mine are installed right now not only incorrectly above the radiator, but the wrong way round too?

I've noticed that I've got the plastic cross visible above the fan blade with the current setup/incorrect placement, whereas in the pictures you've shown me.. The fans are the other way round. Once I moved them to the underside of the radiator, should I then also install the fans flipped so the plastic cross is not visible? (So it looks more like image 2 rather than the first image on my computer)

Why have they also been not only installed on top of the radiator but with the fans the wrong way round?

I don't know why they were set up like that. I've personally never come across the H150 being installed with the fans upside down on top of the radiator. The majority of people use the fans (underneath the radiator) to push the hot air in the radiator out of the case.

I would personally advise calling PCSpecialist or writing to them and ask if there was a specific reason they were installed this way. Either it was a mistake or whoever built the PC had a specific reason for doing so.

I think it was done for aesthetics, as it has a glass roof.

I rang them up (tbh I did get it a year ago so it's been a while!). The guy said that he would have also installed them on the under side too.

He did mention that it could have been possible that they built it in the way you guys are suggesting but during testing they perhaps decided to change it for some unknown reason (honestly not sure what that could even be given what you guys have said), but obviously that's all speculation.

Regardless he recommended me to change the fan location and to check back with them if there's no difference. I'm really hoping that changing the fans tomorrow will yield in a much cooler PC when gaming

Quite possibly! I rather have it not on constant 2350+ RPM than looking nice lol!

I was getting concerned that I might not have enough allowance/space by the top of the motherboard but I think it'll be fine. The fans might slightly cover the lcd display, and I might have to move the exhaust down a tiny bit but yeah the fans should still fit in there so I can't imagine that would've been the issue either.

The best way to check it's working correctly after configuring the fans would be to run a stress test or benchmark test. You could try either Heaven Benchmark or 3DMark (Steam, requires in-app purchases).

Hopefully this solves your issue.

Edit: The person you called on the phone seemed to have the right idea at least. If changing the fan location doesn't improve your thermal/noise issue, then it could either be a thermal paste (simple fix) or pump issue (requires an RMA). Best to test these issues step by step though.

Update!

I've moved the fans to the and I can see why they opted to put them above. The fan to the left on the radiator was hitting the LCD display on my motherboard, so the plate that the radiator was screwed to wouldn't sit flat. But I managed to make it work anyway by putting some risers on the screws and now it sits nicely.

The first thing that I've noticed is that the fan noise is massively reduced. Even if I manually turned the fans go up to 2000+ RPM, this is probably because the fans are now inside the case, so the jet engine noise from them being above is no longer there.. It's more just the audible gushing of air. So that's a big win for me.

As for temperatures, I think we have success there too. It's nothing crazy, but before hand when pushing my system on Cyberpunk 2077 or Baldur's Gate 3 (with best settings I could get via recommended which is always usually ultra/ray tracing on a 4k screen etc) The temperatures could go as high as 47 as seen in initial screenshots.

But now I'm happy to say that the H150i Elite Capellix coolant temp is around 41-42 C, peaking at 43ish. If I open the window since this room does get very hot quite quickly, it'd easily maintain 41-42 (or lower) but I'm impressed that after still gaming for a couple of hours, it doesn't exceed 43 once the room temp goes up. Browsing temperatures without gaming is around 33.5 - 34 C, before changing the fan location the PC's idle coolant temp was 36+.

After some research I've heard these new temperatures are expected when the PC is under a heavy load/gaming with demanding games in 4k? Either way to me, the fact it settles in the early 40's when playing demanding games is a huge improvement! Thank you all for your advice!

That's looking really promising, I think that's a far better configuration.

Bravo

Glad to hear it. A 6c decrease in temperature and a 43c pump peak temperature is a great outcome.

 

[Scott]

I would definitely look at a change to the fan curve. Aim for a peak of 60C and level out the whoosh a little.

A peak of 60C on what?

Apologies if I misunderstand what you're talking about here. I've solved the original issue of higher coolant temps when gaming after changing the AIO fans to inside the case. I now get a peak of 43C coolant temp when gaming on a demanding game.

The actual temp of the coolant isn't something I'd be overly worried about unless it gets alarmingly hot

The temps of the actual chip itself are the most important thing

Ahh, yeah I wouldn't be too worried about the coolant temp. All that matters is the CPU temp. What temps are you seeing there? I thought the cooler was working crazy hard to keep the CPU in the 40s .

My CPU peaks around 80 when really being pushed, but my fan curve is pretty gentle and only starts to really come in once the temps ramp up. Means my system is silent most of the time. It's worth tuning a proper fan curve in this manner. Every chip operates differently so most fan curves are either too aggressive or completely linear.

Ah ok. Nooo haha. My H150i coolant temp peaks around 43Cish to keep the 12900k CPU temps 60-65C give or take when gaming. I think I have a decent fan curve maintaining that, it's usually is around 1700RPMish at that temp.

I suppose I could allow the coolant to get higher than 43C if I reduced the fan curve but I'm ok with where it's at now/how hot the CPU currently gets. Since it's chilling in the 60's I think that's fine? I've also heard that apparently you ideally don't want your coolant temp to get too much more than 10C above idle temp, which in this case for me is 33-34C. So it going to around 43C when gaming on something like Cyberpunk seems about right?

 

[Scott]

As said, I wouldn't be overly concerned with the coolant temp, the CPU temp is the main consideration. Different chips will affect the coolant temp differently so it's not a good metric to measure.

60s is quite low for that chip. As long as it's not noisy and not bothering you then I would say that's all good though. If it gets to the point of being too noisy, I would change the fan profile a bit to allow the temps to creep.

Yeah coolant temp literally doesn't matter as long as the CPU is staying cool and it doesn't starting boiling the coolant

yep just focus on your CPU temp. if you look in I cue you will see that there is a shutdown coolant temp, mine is set out of the box at 70c H115i cooler. my fans never go above 1400 rpm, almost two years now, and with my fan curve, never had any issues and the coolant never got anywhere near the shutdown figure in icue.

If you are happy with how it is then great. Mine is just set to run as quietly as possible for my liking , and no issues
