Dually Taisol CGK!

Another creation of mine, two fans sitting on my CGK742. The purpose of this having both fans offset pushing air right to the middle of the sink, the hotest spot. As with having the heatsink mounted in the middle of the sink creates of dead spot of minimal air movement, cause as fan do the blow out in a wide angle.

A pic of what if looks like

Id imagine this might be quite effective, the overhang helps to push the hot air exiting the sink away and cools the northbridge thats nearby. The fans i have setup on there now are no louder then a Panaflo 80mm L1A, each 60mm fan blowing 16cfm each.
I tried to incorperate a feature you see on some heatsinks out there like the GW CAK, i set the platform 4mm gap between the heatsink and fan blades. This will reduce air turbulant noise. You'll notice i didn't follow the platforms all the way to the edge screw holes on the fan, I tried that on my first attept and i chopped em off cause they were unnessary cause the center 2 mounts held em upright just fine without em, rubber washers were put inbetween the fan and the platform.

Anyways im freakin tired 🙂 Lemme know what you think

My other taisol mod:

What brand/model are the 60mm fans you're using? Adda maybe by the low CFM?

How does the cooling performance compare to using a single 60mm fan with slightly higher output and about the same noise as the two 60mm fans combined? Do you think it'd be enough for a heatload of about 60-70 watts that some of the hotter Athlons are producing?
 
I haven't tested it yet, im waiting to build my CPU heat simulator that should be producing about 84watts of heat. Then i'll be able to test from many varents of fans from delta38, down too and adda 16db fan. Different configs using my 80mm taisol adapter, or using this dually platform or the 80mm single fan platform thats in the making.
The center fins are totally ignored in stock config and just builds up, so effectively if you keep the center fins cooler you'll be able to keep the cpu closer to the ambient temp.

The fans im using are Sunon KD1206PTS3 they are listed on my Fan Page 25db, but cause they are sleeve the loudness of em sounds no more then a panaflo 80mm L1a at 21db. Also with the sunon sleeve models the hub is smaller and the blades are bigger.
 
Hey, it might be a good idea to rotate the fans 90 degrees, so that the air has a better place to flow out of, when they are in that direction, the air (in it's spiral path) is going to be running right into the fins, you should re-orient the top so that the air runs parallel to the fins.

Paul Hilgeman. You may also want to use the screws and metal that is on the HS, and then use caulk to mount the fans instead, it will transmit less vibration.

Just some thoughts, but I cant wait to see your data, put a notice in this thread when you test them so that I can read it.

Thanks,
Paul
 
Bump!

I really curious about the test results. I found an user in another forum using dually CGK760 to cool a 1@1,5+ GHz Tbird at 2,16V, which seems quite impressive...
 
I borke a fin off my stock taisol fan, it still works but it vibrates everything, so until i can get it replaced I put 2 40 or 50mm fans from an old slot heatsink on my Taisol. Motherboard monitor is registering it as lowering the temp, but my question is, do you think these lower temps are from the extra air off the sides affecting the Thermistor under the proc?
 
Nice! 😀 I think that has a lot of potential. I'm really interested in what the results are. That could also reduce noise by using two slower fans rather than one fast one. 🙂
 
I tried two 60mm. fans one next to another on Alpha PAL blowing towards the CPU but surprisingly this would help lower the temp. by 3-4C, only with the case open. However, using the normal PAL fan sucking air is not affected from whether the case is left open or not???

And yes, it is very quiet, basically as loud as the loudest of both fans but not more. In my case these were YS-Tech 26CFM and Delta 20CFM.
 
I'd be very curious about comparing this setup to the same heatsink with an 80-60mm adaptor and a good 80mm fan. It would seem that the adaptor funneling air down to 60mm would elliminate the "hot spot" found in the center of most fans.

It seems that fan adapters work much better when sucking air off the sink, rather then blowing air onto it. I think it has something to do with so much air getting pushed in and nowhere for it to go. I think they would work a little better if they put a couple more exhaust holes on them
 
Im sure this would perform better then the gerneric 60 to 80mm adapter. In fact those adapters perform worse then the stock config. Moving down too 60mm from 80mm from a fan that likes to open up, it gives it no room to breathe and the air is too resticted. Slapping a 80mm fan right on the cgk will perform better then with an adapter even with the overhang and excess air wasted, due that the fan can move more freely the air being pushed out and isn't closed in creating presure on the blades making it very inefficent.

If you must use an adapter 1 way is like the 1st mod i did, its only closed in too 60mm on two sides, but uses the full 80m width of the heatsink. The wider sides alow the air to pass through alot smoother.

<< I think they would work a little better if they put a couple more exhaust holes on them >>


The air would go out the holes then. They should include a built-in shroud and have the fans suck out.
 
MrHelpful, that is the idea, if you can exhaust some of the extra air you don't have all the pressure on the blades, therfore they cool better.
 


<< Would this work with the stock fan and a 60mm sunon next to it? Thanks. >>



Sure Doomguy it should work fine, you'd still get the same benfits.

Should have some results soon!

I got it running breifly in my old k6-2 500 @ 600mhz that pumps a good 45 watts i think it was, look pretty good! But anyways, im still waiting on the supplys to build my CPU heat simulator so i can pump out some real numbers, and start doing the comparing.
