Pleasant surprise for 4850 owners with stock coolers!

Hi all,
After breaking the fan fins of the stock cooler of my GeCube 4850 i was unable to use the card some days. Few days ago i bought this cheap yet effective cooler locally (second hand) and ran some benches, hence wanted to post the performance results.
Check the product here:
DealExtreme: $9.90 QQ Wizard Video Card Heatsink Cooling Fan for Nvidia and ATI (2500RPM)
I bought this for Rs. 400.
First of all, i'd like to tell you guys that i was not really expecting some serious performance from this one, the reviews said its just slightly better than the stock cooler, hence i made a make-shift airflow jugarh using two Scythe kaza-Jyunki 110 CFM fans, all done with cable ties and double sided tape. I hate parmanent damage/modification of my hadrware


1) This is the contraption i made:




2) Closer look: Notice use of cable ties







3) This is how you can connect fan to this metal part which is detachable in CM 690, others can look for something like this... idea is just to hold a fan and fit it in cabbie rear......







4) Whole thing fitted....




5) Cable ties are really under-rated ..... its very useful...




6) This "jugarh" worked for me in my CM690, you can anything similar...





Now the real world temps:

# 4850 overclocked FUR bench (load) test with stock cooler 88 frakking degrees (after cleaning heat sink same day )



# With the new cooler and fans on full RPM, 4850 overclocked FUR bench test... 54 sweet degrees



# Just for kicks: IDLE temps: in 20s...




Finally,

There is a drop of 34 degrees between load temps which is amazing. Since the stock cooler bench was done in november and its colder now (benches with new cooler were done 2 days ago), you may stiil expect a

drop of 25-30 degrees on LOAD temps depending on the fans you use and local city temps. Not bad for Rs. 500-600 IMO.

Thanks.

PS: In summers you can grab these DealExtreme: $3.38 Aluminum Alloy Chipset Heatsinks for PC Memory Chips (8-HSK Set) cheap aluminum alloy chipset heatsinks to cool the VRM err... this thing:



This thingy can also be done with "open" stock cooler, you just need to open the red plastic cover of the cooler, try not to touch/clean the fan as it is very brittle. Coverless stock cooler:



Use cooler like this and use 2 120mm fans below it, no more high temps....

Just another info: Cooler with fans eats up only ONE pci slot on my IP35-E mobo

awesome man, repped for the pics

Very cool. I wish I was half as handy with electronics. Everything I touch dies.

gr8 tips buddy

Zip-ties on fire!!

Nice effort.

Why dont u attach the 2nd fan with the support using another zip-tie instead of simply making it rest on it. Once again, nice efforts.

Congrats on the good ol' contraption.

Thanks man
Nice idea, will do...

nice work baby vivek

nice , my idea worked for u

Hows the noise?

what i do is use a fan to clear the air from the rear of the card...
lot of hot air accumulated in that region due to enormous CCF n that air needs to be moved.
temps remain around 44c idle n 58-60c at load due to it....compared to 58idle 75c load earlier.
will surely try this this along wid fan blowing on the rear of the card....hope it will keep the card close to room temp at idle.

thnx for the heads up

Good temps yaar

Good ghetto setup

nice work there .............
it's good that a 400bucks cooler does it .

[OT]
but those SCHYTE FAN'S costs more than double as to cooler..........NO wonder other FAN'S like AMIGO (175 bucks fan) will do the same for it (with lot's of noise offcourse :p ) [/OT]


this type of cooling system was also done by 'supra' ,in review of 4850 :-
