So, i was recently ask to explain a mod that helped me reduce my temps by 5c+....
http://www.tomshardware.com/forum/253441-29-sunbeam-core-contact-prolimatech-megahalems

I decided to create a new thread explain how it was done....

I was having trouble getting my cpu stable a 3.7 with 1.432v due to overheating with OCCT program... The temps would immediately jump to 58.0c - 59.50c. After a couple of minutes it would fail... :fou: My rig is set up in a second story room which tends to get hot. I decided to create a mod that would blow whatever cool air i had in my room directly to the fans heat sink.

I went to my local Home Depot and found this light weight coupling for $2.97...

Went home and gather a glue gun, blade and electrical tape. Place the coupling on top of the Scythe DFS123812-3000 "ULTRA KAZE" 120 x 38 mm Case Fan. I put a couple of dots of glue where the coupling and the fan where making contact. Then wrap the extra holes with electrical tape (only tape i had available :kaola: ) so it would push the air thru the coupling instead of the holes.

I looked inside my case and notice that the "b" shape of the coupling was going to help me clear the ram and 24pin socket.

I inserted the coupling with the as soon in the pic.

This mod help me lower my temps down 6c+... Cheap, ghetto, stupid? Maybe, but helped me with my overclock... :sol:

Here's a pic with my overclock info http://rapidshare.com/files/262597432/my_overclock.JPG
Pic will be available for 90days

I would add a bare copper ground wire around the end of the plastic couplings output, and ground that wire to your bare metal of the case somewhere.

Air flowing through plastic will create static electricity, so you need to ground the plastic end towards the components to be on the safe side.

Raw bare wire around the end, insulated from the plastic pickup to the ground point.

Good Job! And rather ingenious to solve your problem. Ryan

Thanks a lot for the post man! I'm guessing you cant put the front cover for your case with this mod, but it still seems really cool....gonna have to start making measurement with my case :)

If your case has a side vent you can do the same thing with a little flex hose and using the fan as an intake...use the hose to direct the air where you need it the most....either to the gpu fans or the cpu cooler.

I experimented with that myself but you get a roller coaster effect from it, because the compressor doesn't run constantly, while its running you have extreme cool, when the compressor cuts out the temp rises until the compressor kicks back in.

The temperature variation doesn't give you solid enough constant temperature to gain real solid constant OCs, you're actually better off allowing the best ambient room temperature you can get to rely on as a constant temp, and thats pretty important when air cooling.

But thats just from my own personal experience, RaPiD987s direct air tunnel injection pulling in a constant ambient room temperature is very effective.

you will get some fluctuation out of it, but since Ac is set to deliver a constant ambient temp it won't be too extreme. Even when the compressor is not running it is still pulling the cooler ambient temp into case. It is not a real attractive setup, but for people who need the extra cooling it can make the difference. The customer I most remember doing a setup like that for lived in AZ and had no Ac in their office (it was a non profit organization) We got a tiny portable AC unit to use as a dedicated cooler for the PC that is left running pretty much all the time the PC is on. The rooms ambient temp is usually in the high 90s, but we were still able to get a cool stable 4.0ghz on their i7.

What about using an aluminum dryer vent and covering it with duct tape? My case is set up great for a front to CPU vent solution. Side venting would not work as well. Was actually thinking of attaching the front intake vent to the CPU cooler. (basically set up as the OP) I was thinking to cover it in duct tape to help reduce the chance of arcing or shorting out anything. Would this work?

you can do the same thing with the flexible toilet tubing! , this also fits perfect without the need for tape , and since the flexible tubing has got springs of metal in it , it can be cut and straightwened to ground with ur case!

Hope this helps anyone with modding for airflow.

if you seriously need airflow , why not try a antec skeleton case and buy a stroung household fan , that peeps use for summer , leave it on max setting directed at the antec case , which will be stroung enough to give you a remarkable amient temp and also stroung enough to blow crap/dirt from the skeleton case!

one again im throwing ideas out , hope this inspires or helps anyone!
