Introduction: Better CPU Cooling

Picture of Better CPU Cooling

After some recent google-ing and computer upgrades I have discovered a way to get your CPU up to 7 degrees Celsius cooler.

Step 1: Parts Needed

Picture of Parts Needed

For this instructable you will need the following
a $5-$10 80mm or bigger case/CPU fan (I used a 92mm cooler master CPU fan)
a dremel with a with a metal grinding disk or any similar tool
a spare 3 or 4 pin fan spot on your mother board *note: 4 pin fans work on 3 pin spots*
$1 garbage bag ties
eye protection

Speedfan (program)
***If your case does not have holes or some ventilation in front of the CPU fan area you might have to cut a hole and put some mesh or something there***
**If you don't have a spare 3 or 4 pin can spot you can spend an extra 10 dollars to get a fan like this one Arctic Cooling Arctic F9 PWM 92mm case fan**

Step 2: Cutting

I put the fan on the outside of the case because there was no room in the in side of the case but if you have a big case with lots of room you cam put it on the inside.
If you already have holes or vents in front of your CPU fan then you don't need to cut a hole there but if that is not the case then you need to cut a hole in your case and put mesh there.
I already had ventilation so I only had to cut in a little hole for the wire. also make sure that the hole is big enough for the plug to fit through

Step 3: Mounting the Fan

Position the fan so that the end that the cable is nearest to the hole you made for the wire.
Make sure that when you put the tie into the mesh or venelation on your case that each end of the tie go in different holes.

Step 4: Finished Product

this simple case mod brought my idle CPU temp from 43 to 40 and my average usage temp (Firefox 4 beta, ATI Catalyst, spybot with teatimer, zone alarm, bitcomet, netgear tool, avast and tuneup 2010)

My CPU cooler cant move any air, so my case heats up to about 100-110 degees F, i just use the case as a foot warmer under my desk a lot of the time...

edit- i now have a crazy case and fan and my cpu never goes above 20degrees C under a max load

it all depends on what cpu u have but now i have a custom computer which i will show pics of in my next instructable

Well, that's an interesting way to add a casefan.While you're hacking on it you might as well cut out a circle under the fan for better airflow.

if you are talking about how i put the fan on the outside of the case or the ties that i used to tie it down. if you are talking about the position of the fan being on the outside of the case it is because i had a small case so it would be all cramped up inside if you are talking about the ties... it is because the screws that came with the fan are too big to fit through the tiny holes and i don't want to bother making new holes.

I've got a 120mm on the outside of mine. I used a drill to make screw holes and tin snips to cut out a circled in the middle. The power line goes in through the big fan hole. Use the fan itself as a template for the hole. I used nails to mark the spots to drill screw holes and drew a circle around the blades inside the fan to mark the big hole.

If you are looking for better CPU cooling, look into something called water cooling.

At the time (after upgrading most of my graphics card, ram, power supply, thermal paste and the hard drive) i had about 12 dollars left and a spare cooler master fan so I found some garbage bag ties and bought a 9 dollar fan with an adapter so 2 fans can be hooked up to one spot. this instructable is for people that don't have 50 dollars lying around

Hi I f anyone has suggestions plz post them then I will make changes. Also apparenty this works better than having a funnel from the cpu fan to the case vents. can someone verify that for me. Thanks
