Pardulo what is your ambient temperature during the time of record?

**Pardulo** · 03-06-2009, 08:16 AM

Sorry, you right. The temp was about 18,5-19° max.

Last week, I found a brand new AVC socket478 CPU cooler in my room.
I already forgot when I bought it... I think it lives in my room about a year ...

How can I use it.......:time: :time:
OK, I will mod it into a chipset cooler for my MSI K8N Neo2 (nVidia nForce3 Ultra) ...

More pics pls visit my blog! ^_^

Here's what I did in 2006 to my 7900GT-512 SLI setup:

Above, you can see that this is a Zalman CNPS-6000 Cu cooler that was popular for cooling Thunderbirds back in 2002. I had it lying around and thought it was the most beautiful flower IHS out there, and I already did custom modding to 9800Pro cards in 2004, so I was curious about this one..

Above are a couple of strips of aluminum metal sheet that was cut out and drilled with holes, used to hold down the hinge that was made for the CPU socket.

Notice the 4 screws in the holes.

Putting the bolts on..

Tightening the bolts by holding it and turning the screw.

Then I spread out the fins back to the original position. The fins were clumped together so I could access the bolts/screws.

3 powerful fans blowing down from top. Notice the small 40mm fan from Thermalright, sitting directly on the flower heatsink. It's a 7000rpm 40mm chipset fan from Thermalright NB-1C. The Zalman bracket was used for the 80 and 92mm fans.

For the first card in SLI, a Sytrin Kuformula (Masscool) VF-1 cooler was used, sans the extremely loud, ugly, and oversized blower.

Another picture, one that shows off the lights. In this one you can see another fan that is a 70mm 4000rpm "SLi" fan that came with Abit Fatal1ty AN8-SLI. It helped to really push down the air through the Kuformula heatsink.

The Opty 175 was cooled by a Big Typhoon with a 131CFM 38mm x 120mm fan so it ran at 2.9GHz dual-core at 46 degrees max. If I let all those 14 fans run at maximum, it would be almost as loud as a Vantec Tornado!

The temperatures were great, and I could overclock those 7900GT-512MB cards to 7900GTX levels, so that the performance was identical. Those cards were overvolted to 0.05v more than the GTX cards. What I liked about those GT's was that the PCB's were shorter, so I had better access to this "dumpster" case that I kept on modding and gutting out.

Whaddya think? The PSU was a red Vortec 600W SLI, which was great with 37A on a single rail back then when Athlon64's were fussy with <18A split-rails. See here: ( I was always adding/changing stuff, and some of the things were incomplete there like chagning the Plextor bezel to black, etc.. , and doesnt show everything... That was from 3 years ago.)

I can add more later when I find older pictures of this really unique heatsink I made--it was a reversal "funnel" one that sucked the bejesus out of the heatsink instead of blowing air onto it.

Hih.

**Bo_Fox** · 06-21-2009, 10:30 AM

Once upon a time, 5-6 years ago....

Here, you can see a 120x38mm fan on the top, connected to a 80-120mm fan adapter, connected to a 60-80mm fan adapter, that is connected to a 60mm copper heatsink.

The 60mm pure copper heatsink is OCZ Gladiator 3 that had a huge thick copper base and skivved fins. It was the best out there, even beating the newer, bigger Volcano 7+ from Thermaltake. It was also heavy.

Anyways, the 120mm fan was mounted so that it blew air upwards, sucking air through the copper fins of the 60mm heatsink. Imagine 131CFM of air entering through those fins. I taped the whole thing up, to make sure that all of the air would only enter through the fins, from the bottom. I could feel hot air blowing out of the fan, and it allowed me to overclock my Athlon XP to 2.7 GHz at 1.8 volt, which was nearly record-breaking for air.

It worked amazingly well, beating anything else out there at that time. Nothing could touch my custom cooler, period--not even after Thermalright released their first copper heatpipe cooler (the SP-97). Yes it was loud, but that was the only way back then in the old days, long before the rise of monster heatpipe coolers.

extreme cooling indeed

**cirthix** · 07-20-2009, 01:33 AM

@pardulo: Impressive work, keep it up! Love the low temp difference from idle to load

**Bo_Fox** · 07-27-2009, 11:47 PM

Dang, I don't think I can find pictures of my custom-cooled 9800 Pro from the same time period as my last post above.. gotta look around more, maybe I'll dig it up.. it's a basic CPU cooler, but with a reversed fan. The base had to be dremel'ed with a square outline, so that it would go over the external shim that was raised slightly higher than the GPU chip itself. The 9800pro was volt-modded as high as possible, and I could feel hot air blowing out of the heatsink, which was awesome to observe after taking off that puny stock heatsink that was really pathetic.

Hello to everyone!
My research in custom heatsink's

Glacial Tech Igloo 7700MC CPU cooler on north bridge.

Arctic Cooling Accelero S1 vga cooler and Thermalright HR-05 IFX SLI on miniITX motherboard.

More pics of that ITX setup please!

Wow, NeuroNoise, more pictures!!! Those are great, and you're not doing justice to them with just 1 picture each!

Ok, so I have been bored today. Was thinking of making a custom shroud for my graphics card. I want the air to blow through instead of down onto the GPU. So, doing some quick CAD sketching it looks like a 50mm fan and a 40mm fan will be just stand about 2.15625" tall on the PCB. Would have to use a 40mm to sit on top of the power connectors. My guess work puts that as a triple slot cooler. Question is if this would be beneficial or not before proceeding. I only have a junk 7600gt and my 4890. Dont really want to destroy my 4890 leaving only the drastically different 7600. With the 4890 I could just mod the stock cover to accept my fans. 7600 will require complete fabrication. Would the work be worth it? Can a 50mm and 40mm fan blow enough air to cool the HS better than a stock fan? It would allow good cooling for SLI or CF, but the problem is the 3 slot design. Most mobo have a single slot between PCI 16 slots so dual slot can utilize CF/SLI. So, my design would leave a slot open but at that point, provides nothing over running standard cards in SLI since there would be space between the stock cards also.

Probably stupid and wont work huh?

Nooooooo...., do NOT use those tiny fans!!! The centrifugal fan gives so much more pressure, forcing cool air through those fins. Plus, to have the same amount of air blowing through, you'd have to have those fans running at insane RPM's, at over 7000rpm each. It'd have to be sitting right next to the heatsink for there to be any pressure at all. Well, It could still work for the 7600GT just fine (cooling it nicely), but the 4890 would definitely overheat and crash because the high heat dissipation threshold is not being maintained.

I put my Akasa Neo Vortexx on my Sapphire 4870 1GB card and it actually cools a lot better (about 7-10 degrees C) while doing the OCCT maximum stress test. With this stock cooler

, it would not stop climbing over 100C as I was running Furmark or the OCCT GPU test, so I do not know how much WORSE this cooler would do than the Neo Vortexx, which is a rather quiet cooler by the way, maxing out at 90C in Furmark but peaking at 70C when Folding..

Also, you could use Sytrin KuFormula VF1 Plus and a different fan blowing down from the top. (See my above post, a few posts up, for pictures). I never used the centrifugal fan blower that came with the cooler because everybody kept on saying that it was way too loud, especially at high setting. Heck, you could mod that blower to move it across the custom heatsink from the side!

**Power5** · 08-07-2009, 05:02 AM

I like that akasa, hate that its blue though. I like the other akasa vortex cooler that's red better, but has a lower cooling capacity. Where did you get yours from?

**Bo_Fox** · 08-08-2009, 12:28 AM

Got mine from newegg.com.. now, the vortexx neo is sold out everywhere except for here: http://www.sidewindercomputers.com/akvoneocoblv.html

What are good (non computer related) devices to scavenge heatsinks from? My father has lots of old electrical equipment in the shed. I have some good ideas to customize the cooling system of my server, but can't be bothered to buy some new heatsinks.

You will have more sucesful findings on AC to DC power supplies, not talking on computers, but general power supplies like linear power supplies. Most of them comes with huge heatsinks.

push/pull with a rubber band

Good luck with the rubber band. I used to hold on a ghetto fan setup on my memory with rubber bands, the heat kills them pretty quickly. They'd start breaking after about 2 months.

[QUOTE=skugpezz;4002953]push/pull with a rubber band

Yeh like Camride said, it will start to break pretty fast.
I found it was much better using cable ties, holds on just as good and will last for years
