My Antec 1250 water-cooled CPU fan makes a squeaking noise every 5 seconds.
When it does this, the other fans drop their RPMs down by about 15% for about 1/2 second. I can observe the slowdown by watching the RPM monitor in the BIOS. So every 5 seconds, I hear a squeak, and then the other fans all slow down a bit.
What could be causing this? Is the water pump clogged or blocked?
Here is a video that demonstrates the noise:

EDIT: In BIOS, under Voltage, it reads
CPU = 1.28V
5V = 4.97V
3.3V = 3.24V
12V = 11.94V

1confirm that you are not almost at max power capacity. – Frank Thomas – 2016-06-22T12:56:38.640
I added an edit to indicate voltage levels, is that what you mean? – jsp – 2016-06-22T13:24:26.440
I am more concerned with overall wattage and whether you are just under the line your Powersupply and AC source are providing. Do you have a UPS? its usually easiest to evaluate at the wall. – Frank Thomas – 2016-06-22T14:14:33.240
No, I am not on a UPS. It's plugged directly into the wall. – jsp – 2016-06-23T00:10:32.937
Sounds like a power issue or a thermistor fault. What is your power supply? – Ctrl-alt-dlt – 2016-06-27T07:37:27.733
I have a Corsair HX850i power supply -- 850 watts. – jsp – 2016-06-28T11:21:22.957
