Would this work as a passive setup?

post #1 of 7
Thread Starter 
I just got my media server/HTPC up and running tonight and so far it's working great. I used some spare parts from my old desktop for this build, the CPU, Heatsink and Mobo.

I was wondering if I could run the heatsink in a passive setup? I ask this because if the HS fan wasn't in there it would be at optimal silence for me, I can hear it over all the fans. It is an Xigmatek Dark Knight and the CPU is an AMD Phenom II x2 550 BE running at stock 3.1GHz.

It is in an Antec 300 case with only the top and back exhaust fans right now. Would this work or would the heat be too much?

I'd try undervolting your fans first. You can do this without a controller:

Also check that your CPU fan is set to be automatically controlled in the BIOS. See how your temperatures are after doing that.

I would pull the fan and give it a try. Chances are your temps will be ok. Then try putting a mild load on it by opening a program or two. If the temps are within acceptable range try a stress testing program.

Also, you could also just swap your cpu fan out for one that is quieter, or buy a fan controller. I think the fan controller is the best idea. I own a Lamptron fc4 that I got for $30 from frozen cpu, and it has made my system silent when I dont need the extra cooling power.

Let us know how your temps are with no fan, and good luck.

How high should I let the temps get before I start worrying?

Your CPU should stay under about 62 under load.

If you're just going for a media center/HTPC, you could try underclockin down to 2.6 or so. It doesn't require much horsepower to play some movies.

I'd stay below 55c if I were you. If you can't get that low, then try to attach a low RPM fan onto it.

Just an update for anyone who is interested. I have gotten some spare time, so I decided to unplug the fan and let prime95 run. It has been running for about 10-15 mins and I have hit a high of 45C. How much longer should I let it run?

I have never undervolted a fan before, how is this done?
