'Clicking' sound from CPU/heatsink

Hello hive mind...

I am unsure if this is a problem or if i'm being neurotic but thought I would post just in case. Around a week ago my desktop developed a strange clicking noise, something it hasn't previously done in its 6 short weeks on this planet. It is really hard to describe the exact sound it is making but it is a constant fast clicking.

On investigation it seems to be emanating from the heatsink/cpu area. Note I have a coolermaster 240 on a Ryzen 7 CPU. All of the fans (case and cooler) appear to be running smoothly so I don't think it is that. I have called PCS and they suggested it was likely an air bubble in the cooler but I'm not so sure that is a plausible explanation. Weirdly the sound seems to disappear under higher loads. I have run temperature tests and all seems to be working ok, which is kind of reassuring.

I have tried to upload a sound file but the forum doesn't seem to allow for this type of upload. Any tips on what this might be would be appreciated.

Yeah, the audio file would need to be uploaded to an external site and then post a link to it here...not sure of any offhand though

Almost like a rattling engine sound...
How old in the machine? Is the coolermaster a liquid cooler?
What are your temps like? (just wondering if a liquid cooler could it be the pump?)

The PC is approximately 6 weeks old. Coolermaster 240 is an AIO liquid cooler. Temps seem to be ok to be honest. I can live with it, it is just driving me crazy.

I'd get in contact with PCS, its not a normal noise for a computer to make.
Are you sure its not coming from a fan? either fan stuck, or something catching?

No I didn’t think so either. I’ve already been in touch and they fobbed me off with it being an air bubble inside the system. Will try them again tomorrow.

Sorry missed the second part of your post. I can’t see anything catching and all the fans seem to be spinning fine. As I said it seems to disappear when under load and surely it’d get worse as the fans speed up if it was something catching? I’m a bit baffled. I could post a few pictures of the inside of the machine if that would help?

That is definitely not right....the inside of a PC should not sound like a Jackhammer (admittedly a quiet jackhammer but one nonetheless). That sounds like a fan to me..maybe there is a faulty bearing or something...it's not unusual of fans of any type with an issue to be louder at slow speed.

Hmmm...just done a search on the internet and it may well be a pump failure (found a video of a pump failure on Youtube which sounds a lot like yours). I would definitely be getting back in touch with PCS about it (unless someone else has any ideas)

Quick update. Spoke to a very friendly chap in the PCS support team and they're sending me a replacement to fit myself tomorrow. I've never done this but it looks pretty straight forward. PLEASE DO CORRECT ME IF I'M WRONG.

I appreciate all of your help as it gave me the confidence to sound a bit more convinving on the phone.

What are they sending you?

Good question...!! They're sending me a replacement 240 lite. The adviser listened to the recording above and agreed that it sounds like a failed/failing pump. Just need to swap the existing unit out, I assume re paste and away I go. Looks quite straight forward, but then it always does.

Replacement received. Very quick service.

A question for @SpyderTracks or @Nursemorph - i am going to repaste the CPU. I have some 99% isopropyl to clean the 'old' paste off, which I will do carefully. The PC is unplugged, the PSU is turned off and it has been sat in that state for 24 hours. There are no other precautions I need to take are there? I don't want to fry my system.

In terms of the replacing the cooler, I have no idea as I have never removed a cooler or repasted in my entire life!! In terms of generally, the most important part is to make sure you ground yourself on something to remove any static before delving in (in an ideal world you'd wear an anti-static strap)...touching a metal tap I imagine should be sufficient or touch the case itself if it's on the floor

The grounding thing had crossed my mind so thanks for clarifying. The old cooling system came out really easily, it appears to be a very simple job. Time will tell whether that is a naive or true statement.

It’s usually better to leave the pc plugged in, but turn off the PSU switch on the back of the PSU. That will ground the case and internal components through the case.
