Cooling Fan McGyver style

[RedVexHK]

OK..... I bet plenty of you are having issues with cooling fans or whatnot.. I just made a purchase for $5.95 +tax for a USB powered microfan.. surprisingly it moves air quite nicely and is very quiet.. and has a cool Blue LED light too.. Now this fan has a flexible metal shaft about 12-15 inches long. I intend to place it inside my low profile case thru one of the open IDE slots plugged into the adjacent USB slot with the fan positioned to blow cool air across the heatsink for my ATI Radeon 4350 HDMI Silent. video card. the soft flexible tough blades will be safe inside.. and of a size that fits and works... the fan actually moves more air than my case fan.. So.. what do you all think??? Inventive?? I'll tell you how much it changes my temp.. Not home atm... be there by Friday.

Deff I need some extra cooling...... hope this does nice.

That sound very innovative, like McGyver would do it. But wait, he would use a chewing gum to fit it :thumbsup:

 

Okay, to be serious, this is only a thing you want to use a short time, right? If you want to have a permanent solution i would try to go another way. If you want to have your Computer very silent (like me) i would suggest to use a fan controller to speed up/down your already fitted ones.

I would buy a new silent fan (like Noctua) which can have a rotation up to 1300rpm (120mm). With a fan controller you can turn them down to 800rpm or off. If you wont by an extra controller you can also use your mainboard connectors and speedfan.

 

Btw, witch temperatures are to high in your computer?

Just putting a fan inside the case will only stir the hot air around.

 

For proper cooling you need to move the air through the case. - In one side and out the other. Best is to have intakes - preferably filtered on the bottom of the front of the case, and outlets - not filtered at top of the back. You can have fans in either or both locations. Most common mistake I have found is having several case fans all either blowing in or all blowing out of of the case. You need as much area for outgoing air as you have for incoming air to prevebt the air from slowing down as it passes through.

 

Larger fans 120mm and up are typically quieter than smaller fans 80mm or smaller. But check on mounting holes and clearance before you buy to be sure what you get will fit

haha reminds me when I had my passive cooled 7950GT...zip-tied a 80mm fan on top of the heatsink :P Worked great :D My northbridge fan took a dump not too long ago and now I have one zip-tied on there too :P Fan that was originally on it was some strange form factor...I just gotta get a new northbridge heatsink :P Ah Macgyverin' though haha :D Good idea ;)

 

But like bben said...ya gotta have proper intake and outlets. I have an 80mm (loud....so loud) in the front sucking air in and a 120mm blowing the air out in the back. The front of the case is also all mesh with filters. ( Also have two vents on the side of the case, one has another 80mm blowing air in right on the CPU (thinking of switching around.) . PSU also has a 120mm fan on the bottom. The two 80s, the 120, and the NB fan are all connected to my fan controller. Cuts down on the noise a bit...but the 80s are still loud as heck. Nice cool computer though :P

 

 

Love my case...cheap too :D

Well... as for intake... the slots where my PCI devices mount is open ..the fan will enter thru one of those slots and blow directly onto the Video card. Air intake will be directly behind and to the side of the fan. the output fan is on the far corner front side of the case... I honestly want to replace it with something that will move a lot more air.So Fan has intake right where it needs to be.. exhaust fan is in front but is not adequate.. (underpowered) this for now is a temporary solution but hopefully will work for now. No Bubblegum.. but I may use a Zip Tie to stabilize it's position.. LOL

An outtake fan is essential and should be the first you try to change / install if you have heat problems. Intake isn't really needed because the air will find its way inside. If you have some holes near your graphic card the air stream will cool it, maybe it is enough for yours so you don't need to mcgyver to much :happy:

 

Only as an example, i have no intake fan, only the normal hole for a fan in the front. My 4870 has one 120mm @ 1000rpm and there is another 120mm @ 1000 rpm for the cpu. The circulation is done by the PSU fan and an optional 120mm which is mounted on the back. This one will only work if the temperature is over a defined point. :thumbsup:

So it is very silent like a computer should be :laugh:

If you want fan Movement check out this case, i have one myself.

 

 

 

 

It sucks out Hot air through the top :thumbsup:

 

Its a Antec Full Tower Twelve Hundred Black Gaming PC Case

Well.... I installed the fan... GAH!!!! the motor was about 3 mm too long... didn't fit.. LOL... small form factor piece of... hmm well actually it's not bad.... Oh well small pc for a small me.. Illiad86 I tried your idea tho.... twist tied a pretty strong fan to the heatsink on my card. it's working nicely. I still left the back of the case open for circulation... anyways.. my card stays at 45 degrees and lower...

[Vindekarr]

I've got a more eccentric set up.

 

A huge 100 MM on the front sucks air through to an even bigger 125mm on the back. But, all the various internals use small heatsinks and microfans to blow the hot air into a central chamber, where it is then sent blasting out the back by the front and rear high power fans. Its massive overkill for my current rig, but it keeps the whole thing room temperature, and since I used to live in a scorchingly hot tropical semijungle, thats a good thing.

 

The most aswesomebadass cooler I ever saw was another bit of crazy McGyvering. A buddy and I found this old water cooler system someone had junked. So, we bought a bucket of used motor oil off my uncle(a mechanic), replaced the damaged tubing, added fuel pump from a 1992 Mitsubishi Starrion sports car as the main pump, and flooded the piping with the motor oil rather than water. It was one hell of a setup-we tinted the oil green, being fifteen year old boys obsessed with mad science, and won our tafe's science fair with our monster cooler. later I stuffed it in a test machine of mine and it really did work well. Car fuel pumps push fluid around very rapidly, especialy on cars of the ere and design type as the Mitsubishi we ripped the pump out of. You see, the Starrion had a Turbocharger in its engine, which meant it needed a very high fuel flow to match the high burn of the engine. Thus the fuel pump, when it innevitably sprung a leak, squirted like a BP oil rig.

lol that's just awesome :D Buddy of mine did the mineral oil submersion rig...actually works lol.
