Cardboard 8800 GTS cooler

[inCore]

A friend and I constructed something that we hoped would lower the temperatures of my 8800 GTS 512. It's basically a cardboard air tunnel mounted on top of the card with an external 60 mm exhaust fan. Pure genious. Extreme amounts of tape were used for this extreme mod.

I professionally checked the temperatures using HWMonitor and ran 3Dmark06 to prove how genious this mod really is.

Here are the temps:

With the fan turned OFF:

CPU Idle: 43 - 43
CPU Load: 63 - 63
GPU Idle: 49
GPU Load: 67

With the fan turned ON:

CPU Idle: 42 - 42
CPU Load: 63 - 60
GPU Idle: 48
GPU Load: 63

Already the idle temperatures speak for themselves - 1 degree benefits are not to be taken lightly. However, the load temperatures are just simply amazing, 4 degrees for the GPU and one of the cores (I dunno why one, non conformist CPU I suppose) of my CPU kept nice and cool(er).



Other stuff and trivia:

I have an E8400 @ 3.91 GHz and the fan speed of the GPU was set at 80% in Rivatuner.

When I had it at 45% and attempted the same professional review of my ingeniously engineered cooling utensil, my screen froze when my GPU reached a previously unseen 87 degrees Celsius. I'll be sure to save money in winter by turning off the heating and letting my family crowd around my computer.

So yes, this is the idea, it clearly works better than anything else ever made and I'm feeling too cheap to

1) Re-seat my stock heatsink which obviously fails at what it's doing

and

2) Buy a proper cooler.


That's all, first post at xtremesystems, I'll keep pushing it (Just watch, one day I will have mounted something the size of most people's cars to the back of my case), good bye.

Your scythe should be 90 degrees on the left or right...The Fan should better cover all of the heatsink and not 80% of it....Thats why you should place it differently.. Cant you ?

More pictures!!!

Looks great, stick a thermometer in the construction and see how much the temperature above your card decreases/increases with the fan on and off.

"Pure genious" Word!!!

Getting the Scythe in was enough of a march through hell to demoralize further attempts - but I'll try sometime when the time seems right. It can be mounted either way (like this or 90 degrees either way) so it's not wrong. The northbridge cooler comes painfully close too (with the fan mounted, it would be buried alive and would never see sunlight again).

As if this wasn't enough, I'm even in possession of an awesome fan controller that will actually tell me temperatures inside my case. You read correctly. I placed one of them buggers underneath the cardboard and waddayaknow, 2-3 degrees lower temperatures with the fan turned on, just like that.

We will for now completely disregard the fact that the fan is louder than the combined force of a mixer, a vacuum cleaner from the 80's and an industrial hairdryer which can also be used to solidify cement, if necessary.

Note the stock E8400 CPU cooler mounted in front of the cooling device, blowing air across and through the whole artwork. I was also kind enough to include a diagram, which I skillfully made using paint, that fully shows the placement of my fans with their corresponding directions.

This computer is a cooling beast, only thing missing are the good results.

A lot of effort here..simply silicone stick fans onto the case ..No damage and easily removable..
Nice experiment though.!

that silicone idea is genious

[BigKriss]

I removed the stock cooler and have put it under water..
Some more pics of the stuck on fans.

Water,btw,dropped my gpu temps by an incredible 24 deg C !

wow... that fan on the outside of the case has got to be the most pointless thing ive seen... it what, cools air thats already outside the case?

I did close to the same thing by putting a blower type fan over my existing 8800GTS fan and holding it there by wedging something underneath it that rests on the bottom of the case and forces the blower type fan against the opening of the 8800GTS's air intake and its own blower fan itsucks air in from the side and pushes it into/onto the 8800GTS fan.

The fan is adjustable in speed via a front drive bay mounted rotary dial. It helps to push a lot more air out of the card, its easily mountable and is easily taken off for warranty or for selling the card.

I like your mod except for that fan on the outside, it seems almost pointless to me. Especially if it has a heatsink covering it (i cant tell if did or not) The only purpose it would have is to accelerate the air coming out of the card. Its pointless to cool the air at that point.

I feel honored that you took the time to register just to inform me.

You're wrong because:

Fans have a clever property of not only blowing air, but also sucking it out. Fans don't actually cool anything, they dissipate the heat and I'm just moving it away.

Also, no, it doesn't have a heatsink.

And besides, if you didn't see the irony in my post I'm sure you'll enjoy the sticker collection which I'm about to post in the benchmarking forum.

This is so ghetto. Appearance is ruined.

that look awsome
