FYI: Even a small amount of dust can cause overheating!

post #1 of 4
Thread Starter 
Hopefully this helps someone else with random weird beeps and reboots.

Background: PRODUCTION rig in sig, stays on 24/7 BOINCing. Environmental background - no pets, no smoking, no dirty city air. However, the system *is* in the vicinity of the clothes dryer which emits very fine particulate that loves to stick inside my computers.

I began to have strange anomalies. A funny sounding beep would be emitted from the PC speaker from time to time. Other times, I'd get a BSOD with a different cause every time. One time it just locked solid. And sometimes it would just reboot like I pressed the reset button.

I keep my system pretty clean with my DataVac electric air duster, so I never thought dust could be the problem. I decided to investigate the cooler anyway, thinking it got dislodged or something.

As it turns out, there was just enough dust in the Arctic Cooler's fins to cause the temps to exceed the warning alarm temp in the BIOS, which is what that beep was. The very fine close together fins clog very easily on these things. I blew it out till it looked almost new, reinstalled, and now I have no issues and significantly lower temps under full load for over a week now thumb.gif

Thanks, I think

Any idea how this can impact closed loop systems like H100i? Haven't noticed anything wrong, but never cleaned my computer since installation

Well, if your rads are full of dust, they certainly are not operating efficiently. The fluid will run hotter and hotter.

First of all, the warning about the lint/dust clogging one's heatsink is worth a rep. Everyone needs to pay attention to dust. It is the #1 reason rigs quit working and suddenly skyrocket in their temps. +rep.

 

Secondly, you are using a DataVac like a compressed air hose. This is exactly what it is for. You can swap nozzles for different effects, but the main thing is you can just use it until you have everything cleaned out. No watching your money bleed out of a can, no having to stop because the can gets cold. +rep

 

Popsicle sticks, wooden skewers, fireplace matches -- put them through your fan blades before you start, but keeps those rigs clean!
