High MB temps? Cool your MOSFET`s and SFF R60 chokes

[ArcticOC]

My MB temperature was way too high after installing and overclocking my dual-core CPU. Under full load the MB reported temps. above 70deg.C.

After the mod the temperature never come`s above 60deg.C

The 3-phase power solution on the Ultra-D, SLi and SLi-dr get very much workload with the new dual-cores, and with no airflow over them, they quikly rise to +90deg.C That may very well bee just fine for a short period of time, but in the long run I`m not so sure if the mainboard would survive.

I`m too lazy to explain in details how every ting was made, so I let the pictures speak for them self.. This mod is mainly for passive cooled systems and people with watercooling (low airflow systems) If you feel asking me a lot of question`s.. well then your probably not skilled enough to do the mod anyways

The chips marked R60 under the zalman BGA-coolers is the HF-noise filtering that is done through SFF Small Form Factor) R60 chokes, they filter out high Fq noise

The sinks on the R60 chokes is stock Zalman BGA-type and the large sink`s on the Mosfet`s is from and old trashed PSU. Had to do some cutting and drilling to make them fit, but the whole mod took me 2 hours.

NEVER SHOULD YOU EVER INSTALL A HEATSINK ON SMD COMPONENTS, EVER!

For now i'm going to assume you either got very lucky or you did not actually put heatsinks on any of the SMD CERAMIC CAPACITORS because that would almost 100% destroy your board and possibly your CPU.

It appears there are mosfets under those heatsinks.. they are not ceramic and are not capacitors

Sorry, my mistake, and yes.. you would shorth/destroy a ceramic cap with an aluminium HS

But you say those chips are Mosfet`s and that is not eighter the case

Hehe what is that on the NB?

Cut up artic cooling 64.

Why didn't you also apply one of you "homemade" sinks to the top heatsink?..that gets mighty hot as well..

So it IS ok to cool those thingies with mini heatsinks?
Was planning on doing the same

But I did!

If you study the picture below, you can see the copper heatbridge I use when the 4V jumper to the memory is activated. Right now I`m just running my mem @ 3,1V, so the heatbridge that goes to the advance RAM-cooler is off for right now!



Look ma.. no fans

Wait, you run 4v with no active cooling!?

Yes, done it before and did it with ease My OCZ VX did not get hotter than 35deg.C running @3,7V

Nice setup dude, I'd suggest getting some foam for your case to deaden the sound, maybe enclose your raptor in it's own little box in the case?

i put heatsinks on the r60 chokes and i didnt notice any temp/stability differences. i used thermal tape though, so maybe heat transfer wasnt good?

what did you use to stick the sinks on the r60s?

i havent tried applying a heatsink to the stock heatsink though...it looks like you used some TIM on the area where the added sinks contact the stock sinks though, correct?

I use ordenary "quick"glue/superglue

The point of having sinks on the R60`s is just to remove ANY heat from the MB, they transfer heat quite well from the mainboard, but the chokes them self dont gain any stability by the mod.

chinkgai: AS5-glue?

you're a freak man.

Thanx!
There is a lot of problems that comes in play when you stop the airflow on a OC`ed system. I have done a dozen mods to get everyting right, but for now I`m quite happy

Lot`s of small sinking everywhere, based on thermal photos of the DFI @ bigbruin.com (Thanx!)

Right now the sound of the Raptor 150GB killing my ears (but I guess I`m a litle sensitive to noise..heh)

Hers some more details of my system, this is just one of many small mods on the board:

Nice pics dude, that is a very impressive passive setup you have. Very cool what you did with the chipset. I love it.

Thanx a`lot

The whole project took quite some time to finish, but the result is prisless. Mucho custom parts I`m tellin`ya. The system OC quite hard while maintaining almost noisless. My dual-core opty 165 can run at 2625MHz (8 x 325HTT) without any problems. But at this speed the workload on the PSU-fan get`s a litle heavy. So normally I run at 2400MHz, and at that speed the 120mm PSU fan rotate @1000rpm (idle), dual prime and the fan rises to aprox. 1500rpm, but the system is not noisy even at that speed

The pics are taken with my shi**y HP cam, I hate it, all 300gram`s of it, but it takes good macro-photos anyways Only paid 120$ for it one year ago

[Revv23]

thats the best silent pc design ive ever seen.

Great work!

[mindwreck]

WOW that is a lot of heatsinks. Your one serious freak about silence

[dymONE]

Nice work !!

This is my supersilent system :


DDR Mosfet cooling
GTO2 Cooling
RamFreezer

[madgamer]

I think this is really awesome. Great work.

[mindwreck]

Are those old slot1/A heatsinks?? are they supported by any means because that looks like a lot of stree to put on the modules.

[Revv23]

those passive alu heatsinks dont wiegh anything. ive used them on ram before, but in a very different fashion.

[cronic]

I have the ramsinks in the pics below and was wondering if i could put them on the chokes that are outlined in orange on my a8n32.

No problem, but your asus have no need for this mod as it`s 8 phaze layout on the board
