Eyghon Posted March 19, 2017 Share Posted March 19, 2017 Hi, I have this https://instaud.io/OES intermittent noise coming from my PC which I'm struggling to track down, I had 4 HD's in there and have removed all except the OS Drive, I have removed the soundcard and moved to onboard Audio, I'm pretty sure it's not from the Vid Card, I think it's either the Mobo (Z170X-Gaming 7) or the H100i Cooler? If I reboot the PC it clears briefly https://instaud.io/Phd when the PC power cycles but then returns, if I shutdown and restart it doesn't return. It very intermittent, it did it yesterday but was 5 days before that. All the temps look fine on Corsair Link and Gigabyte SIV, no warnings or anything.

c-attack Posted March 20, 2017 Share Posted March 20, 2017 That is strange. In the second sample, I can clearly hear the pump under the tone. I have never heard a pump make a higher pitch noise with that even consistency. That said, there is a first time for everything. Is this a H100i (SATA powered) or a H100i GTX/V2 (CPU Fan header powered)? The pump tone sounds like a GTX/V2 version. If so, simply unplug the CPU fan header while running. That will cut power to the unit. No, you will not overheat in seconds or minutes. That may allow to cross one more thing off the list of suspects.

Eyghon Posted March 20, 2017 Author Share Posted March 20, 2017 It's a H100i GTX, going by this https://www.amazon.co.uk/gp/product/B009ZN2NH6/ref=oh_aui_search_detailpage?ie=UTF8&th=1 or this https://www.amazon.co.uk/gp/product/B019EXSSBG/ref=oh_aui_search_detailpage?ie=UTF8&th=1 mine is V2 looking at the pump in the pics.

red-ray Posted March 20, 2017 Share Posted March 20, 2017 It's a H100i GTX mine is V2 looking at the pump in the pics. The GTX and V2 are different, but look the same. What does Corsair Link 4 report it as? You should close down the gigabyte utilities before running CL4 as they fail to use locks so having both active at the same time could cause issues as it does with ASUS AI Suite, see http://forum.corsair.com/forums/showthread.php?t=118371 Link to comment Share on other sites More sharing options...
Eyghon Posted March 21, 2017 Author Share Posted March 21, 2017 It's shown in CL as H100iGTX, Firmware 2.3.0.0, I have removed SIV for now. Link to comment Share on other sites More sharing options...
c-attack Posted March 21, 2017 Share Posted March 21, 2017 That part doesn't quite matter so much for targeting the source of the noise. However, if you had a SATA powered H100i, I would not be as keen for you to unplug and then reconnect the SATA cable to the unit. With the H100i GTX/v2, that really isn't an issue on the motherboard header. Did you unplug it? Did the noise go away? Link to comment Share on other sites More sharing options...
