Okay, stop me if this has been discussed before but:

Here I am 1:30 AM building a new gaming machine for a friend, a nice athlon 64 with tons of ram, killer video card, the works.. and I am installing the Koolance PC water cooling system and a lightbulb goes on over my headhttp://www.dieselplace.com/forum/images/smilies/shootself.gif.

Anyone tried to make a water cooling block for a PMD?? It would be really easy. The 12 volt pumps are out there and you could build a timer that ran the water through the cooling block for a set period of time after the ignition was turned off.

I have been water, LOX, LN cooling CPU's for as long as I can remember to drive them to their limits (yeah, kinda the QM of the computer world) http://www.dieselplace.com/forum/images/smilies/joke.gif

I am going to have to work on this to see if I can do it with a remote mount PMD and see what comes of it. If anyone has tried this, please speak up!

There were some posts on this in that light, even thought of it myself, from USN heat exchanger experiences though it might be something worthwhile, problem was where to find a source of cool-coolant, once the coolant had done it's job picking up the heat, what do you cool the cooling medium down with. In a closed loop system to need a cooler for the coolant, or eventually it is no longer successful in heat transfer.

Then you have to determine mow much flow is required to optimize heat transfer, too little flow inefficient cooling & too much flow inefficient cooling, it's do-able would make a great home R&D project, if you have access to the stuff you need could even get the bang for buck working, but it would have to be cast-plumbed- and resevoir & coolant cooler fabbed & real estate for it needs to be found, not a whole lot of room on these trucks to stick this kind of stuff.

Solutions offered thus far GM;s use fuel to pull heat vicariously thru IP body to PMD heat xfer, least effective IMO, Finned heat sink in engine bay better IMO, Finned heat sink in cab under AC vent, (not enough data for me to opine), Finned out of engine bay in grill better location for finned, best location for finned though IMO would be in filter air box, if engine is running turbo is pulling cool air across fins for free plentiful cooling medium even on hottest of days in stop & go traffic.

I'm currently running the Heath option on the bumper(my location- kit is normally under bumper where my IC is), max cooling while driving, large plate dissipates heat when in stop & go traffic, is this the ultimate solution, too early to tell from my experience going into my 2nd summer with it soon, warranty on it (7yr) will lessen the bite if it doesn't work. My spare is still Kennedy cooler mounted under the hood.

Last option is REMARQ Q new offering just on the market last year, poor initial showing as a group of fails, but company made good and sent replacements quickly and reported back why product failed, I don't know the population of good vs bad, but the product looks promising as the final solution.

Did not mean to get off track MTLION, your concept is doable, might be fun to see it work, if you could figger out a way to do it for low to medium $$$ you could retire soon. Problem is the driver itself is the weak link to all, if it has bad components coolers are a crutch to make them get by, Remark Q is supposed to have come up with a completely different driver not subject to high heat.

No problem TD, you bring a bunch of good thoughts forward. Here is kind of what I had in mind.

The cooling block part is very simple. The biggest thing would be that it is machined smooth and flat for the best heat transfer. Coolant flow would not need to be very high as we are only talking about dissapating ~1000 watts of heat if I remember correctly. During testing you could even get a higher flow pump and put a valve in line to regulate flow. Since we don't have a seawater sump to cool the cooling medium, a radiator or some sort would have to be installed. This could be the most difficult part of this to get correct. Something you have mentioned before, the fan cooled auxillary transmission cooler comes to mind or a heater core.

The SOL-D intrigues me, but after reading some reviews I am not sure it is a route I would take yet. The complaints about AM radio interference kind of turn me off as I am an amateur radio operator and I run SSB in the truck on the HF-UHF bands. I got spoiled from the diesel already and the total lack of engine noise in the radio.

I really like the idea of putting the cooler in the intake air flow, maybe a heat sink with it's fins protruding into the fender where the thing breathes through would do a nice job too.

As I said, this is all acedemic until it is tested in real life. If I were to try this, I think I would also mount a thermocouple in the cooling block to get some idea of cooling efficiency.

I did some testing in this thread give you some idea of the heat we are talking about in real numbers maybe it can help you decide what size cooler we should be looking at.

Wanna do something really cool? Besides ignoring all those Pentium cooler schemes?
(First, just put the FSD on a heatsink, move it out of the engine bay and into direct frontal air flow location)

Head on down to your fave pc joint, pick up a Thermaltake digital temperature gage\controller, route the t-probe out to your PMD, install the dtm in your cab, and you'll always know the exact FSD temp.

And remember, you saw it here, first. (same as mailing myself a self-addressed, stamped proof-of-originality document, right?)

GMCTD,

That is exactly what I was thinking about for a temp display. Pentium cooling? No way.. gotta cool Athlon 64's and GeForce chips.

My apologies, nv - guess we musta been composing at the same time, cause I was responding to your 03:34 post - takes me so long to edit, I missed the 11:02 post.

Btw - I had thought those Gold and Silver and Copper thermal towers to be awe-inspiring, also, but quickly dismissed them as not viable, same with a peltier junction.
FSD just works better outside the engine bay - my choice is in the turbo intake duct, pre air-box.

FSD is on the Inj Pump (which renders it as PMD), and has been since Sept '01, as part of on-going testing - when I move it, it's to the duct.

Also btw - I'm currently building a P4 for DOOM-III, so I've been nosing around, reading as much as I can get my eyeballs on, playing catch-up from 2001 and a PIII-800.
Man! 800mhz-up FSB, Intel 925, Hyper-threading, 1gb DDR2 ram, 256mb ddr video ram, Open GL\Glide\D3D on one PCI-E card, DX v9.x, 12mhz serial USB.

I got seriously way behind, dude...........

The intake duct sounds a lot easier than a water cooling scheme. However, the thermaltake monitor I really like. It could show an impending PMD failure, The thing that really drives me to water cooling in PC's is noise.

I stick the athlon 64 route for my game machines and if it is in my machine, it says Nvidia. http://www.dieselplace.com/forum/images/smilies/rockon.gifI have done some insane overclocking in the interest of "how fast will it run on LOX or capped with dry ice"

I got a spare FSD off ebay a while ago and it works fine on my truck. I retorqued the screws and I plan to mount it and use it for everyday use and keep the 8 month old one thats on the 5521 as backup.

It was just a "It's late, I'm building and have had WAY too much coffee" idea.
