Noisy Seidon 120M

[Wraith]

So today my Seidon 120M started again with the annoying clicking/tappety/woodpecker noise almost as though there are air bubbles in the pump, now I'm wondering is anyone else getting this noise or similar from their Seidon cooler? And what have CM said about it?

This one I have now is a replacement to the original one I ordered last year which started right out the box with this noise and DABS swiftly replaced it for me so no need for RMA, it seems to come on mainly after I've been gaming and it's cooling down but with general use and browsing it makes no noticeable noise at all.

Now when this happens the advice I got from Cooler Master was to simply either wait 5 mins and it should calm down on its own or switch off and wait a few minutes then power back on, I can say 100% that it does NOT calm down and it will just continue to make these clanking clicky noises until I switch off and on again...

So what are you thoughts and findings?

Is the fan set to run at 1 speed or is it on a fan curve? It could be the fan bearings.

Seidons are generally quite noisy, especially the pumps ( I should know, I have a 120m and a 240m). To be honest if you're running the stock fans chance are its those. They're crap.

also I presume you're running it off the motherboard? (its actually a good idea as the pumps aren't as quiet underload as their corsair competitors) If so check the settings off it

All the fans are tip top brand new Blademasters and throttle perfectly fine given the CPU temps rising under load and idle.

Yeah I have it all running off the Motherboard CPU/Fan headers and it performs admirably 17c while Idle and no more than 39c under load while gaming (Crysis 2, Dead Island, Skyrim, Just Cause 2), it's just this noise I get after I've been gaming and it cools down sounds like I'm trying to cheese grate an anvil it's bugging me that much I'm seriously looking at either the Corsair H80i or the new Seidon 120v.

add about 15c to the temps as it is AMD. Almost sounds like the fans are vibrating the rad. Try taking them off and putting them back on?

I always account for the 15c discrepancy with AMDs thermal algorithm, the noise comes from the pump/block it's nothing to do with the fans.

This isn't mine but it's the same noise, just find it strange that it only comes on after I've been gaming.. but it does seem to be a common issue having just a quick look through Youtube.

How long have you had your seidon?

This one just over a year, I'm thinking it's going back "Again" just need to get a temporary cooler in the mean time.. the first one did it right from day one and this one has just started doing it, it doesn't always do it just every now and again but like I said before if I switch off and on everything goes back to being fine.

Just get a hyper 212 mate, it'll do the job fine. Seidons are quite noisy under load, I kinda want to get rid of mine in my main rig (the 240 I have in my steambox is fine) and get an Air cooler.

Just been reading up on CM forum apparently this "noise" is caused by a drop in voltage which causes the pump to rattle at low speed, as we know all pumps connected to CPU/Pwr Fan headers need to be set at full speed which has now got me thinking that maybe after gaming something mystical is happening with my motherboard mmmm I think I'm going to molex the pump and get the multimeter out and check the headers for voltage differences.

Oh god the pump at full speed is horrible :l

Post your findings mate

Will do. Thanks for the input though, here's hoping I can shed some light on the issue.

I've got my Seidon in via molex and I've never had any issues with it at all.

Easy way to test if this is the case though - you could put a 9v resistor or swap a molex cable round for 7v and see if the problem occurs then.

With some of the old Corsair pumps some of the grinding issues were caused by motherboards/PSUs giving off more than 12v, meaning the pump was spinning slightly faster than it should have been. It their case putting a resistor on it usually fixed the issue.

Yeah I just did it via Molex and the Seidon pumps just fine but my concern was also in whether or not my motherboard was doing something funky with the volts after being under load.... and what do you know it is! After half hour on Crysis 2 the Sys_Fan header is fluctuating between 11.8v & 8.32v even though in the bios it is set to full speed so it would seem the issue is not actually with the Seidon but my Gigabyte GA-78LMT-USB3 it would appear that either the boards fan header circuit is effected by heat stress or the bios is not functioning properly.... my bios is upto date so i'm going to contact Gigabyte now and see if this is a know issue.

At least we have an answer for now which is good I've seen quite a few people on Youtube having the same problem with 120m and also the newer 120v..
