Solved Help with heatsink fan?

January 1, 2016 at 15:04:30
Specs: Windows 7, AMD FX(tm)-4130 Quad-Core 3.80 GHz/8 GB Ram
The issue started up a few days ago, starting with sound. As it stands, it sounds like a car idling, with an occasional revving sound. Then as for heat, core temp would show would show a large heat spike (Before, it would idle at around 20c, then increase to 50 - 55c depending on what I was doing, be it gaming, watching movies, or running a lot of different programs at once), with said heat spike reaching the high 70s c. Sometimes it would go right back down to the 30s a minute later, other times it wouldn't until I rebooted. As of last night, the fan itself wont start spinning on boot. I can see it trying to, the fan itself would try to turn, but unless I gave it a 'push' with some canned air, it wouldn't start at all.

I don't know if I should just replace the fan itself, or the heat sink it's mounted on as well. I did happen to find the heatsink/fan itself (http://www.amazon.com/MASSCOOL-70mm-Sleeve-Cooler-5T568S1H3/dp/B000HJ98M0). If I need to replace it, should I grab the same kind, or another? Any advice on brands/types?

I don't see a problem with your temp readings & contrary to the above, you can NOT "cook the CPU". All modern CPUs have built-in thermal protection so it's impossible to overheat one to death. The thermal protection will shutdown the CPU long before it will "cook".

If you're still concerned & want to replace the fan or the entire heatsink/fan unit, I suggest you get something decent, not the crappy MASCOOL you posted a link to. In fact, the stock AMD unit with heatpipes is MUCH better than the MASCOOL. But if you insist on "upgrading", stick with a heatpipe design. Do you have room in your case for one of these?

As long as the Fan/Heat sink fits on your motherboard (CPU type) it should be ok.
Are you somewhere in Alaska? 20C idle core temp is kinda low to me.

If the fan won't spin up on its own it needs to be replaced. If you can find an exact-replacement fan then that's all you need. If you go with a heatsink/fan combination you'd need to make sure it fits the hold-down bracket your motherboad uses.

My guess is the fan itself needs replacing.

A way to determine this is to leave the side of the case open and use an everyday household fan to blow across the top of the heatsink.

If the system remain stable the heatsink is doing its job and the fan is the culprit.

The next thing to look at is if the HS fan is faulty or the power supply to the fan has failed. Does the HSF have a two or three pronged connector? Is there another fan power supply on the motherboard (i.e. A case fan power connection) you can pull the cable far enough to plug it into? Try plugging the heatsink fan into it, chances are it won't be a variable speed but it should run at full tilt.

Hi Rivyn,

change the suspect fan **NOW**, to avoid the possibility of serious damage.

Fans are not expensive.

Good Luck - Keep us posted.

Agreed. #1 concern is to not cook the CPU!
