Mounting Fans for G400 vanilla

[Brian R.]

Actually, I would recommend that you use the fan-on-a-box in addition to a commercial fan/heatsink like from

or

I don't think a heatsink alone will do a good job of cooling compared with a dedicated fan.

Brian, that sounds a bit overboard, although I'll agree with you that if I have both a Card Cooler and a Crystal Cooler hooked up on my G400 that it would probably run better than either cooler running alone. That is what your saying, is it not?

Question for those out there espousing the virtues of the Card Cooler, how many of you also have fans hooked up to your heatsinks?

Given that I already run my system case open with a 5" fan pointed into it, would this truly be pushing the "cooling, cooling, and more cooling" principle too far?

What's the concensus?

[LAMFDTK]

No fans 'cept for the CC
The heatsink is on there to draw the heat from the chip into the fins. The CC moves so much air through the Heatsink that it stays nice and frosty. If you "close" off the heatsink with a cheap_O_ fan you defeat the purpose. Hey I have used this method with great sucess, make your own choice all these methods will lead you to the same place---->RAM speed<---limiting factor after heat.


Wait for Paul (ALPBM) to post his now infamous 6X9 side car.

I removed the heatsink from the chip and installed the Tennmax BGA directly to the chip, it uses the plate design instead of the fins for its heatsink which is much better for dispersing the heat (like the P-3 alpha cooler) then I chopped up the Matrox heatsink and frag taped them to the memory chips (both sides) and of course I have a great deal of air being pumped into and out of the case....BWAHAHAHAHAHA!

also, the BGA has pins that snap right into the vid card!!!

Ive got a MAX, (heatsink and fan standard) and a CC.
Plus i have a slot fan 2 slots below the MAX. Works very nice. The CC blows air over the whole card, including the backside. It also helps move some air to my cpu. I can run my MAX at 170/230 but i get a lil image corruption, so right now its at 166/222. Very nice. The CC is also very quiet, much quieter than my PS fan.

Nah...

You guys are comparing apples and oranges. The plate design of the Tennmax lasagna coolers has no resemblance to the bonded fins of the Card Cooler's thin-fin heat sink. The lasagna cooler is stacked plates to fit into tight places. The fan is inside of the plates to minimize height (ala G400 MAX). The bonded fins are a conventional heatsink, only manufactured in a different way to allow thinner fins on the heatsink. The drawback is higher manufacturing cost per unit.

[LAMFDTK]

My point (then i retire from this thread)
Is that the Card Cooler's thin-fin heat sink design is the same as using a heatsink and the CC. just that the fan is not mounted on the fins but is a dual fan mounted a few inches away. The problem with the tennmax lasgna is that it runs too hot. I had one on a stock TNT and I felt it was a waste of money. The fan is down in the heat sink and the sink does not draw heat as well as a stock sink with "extended" fins will. Give me cool air flow through some "fins" any day. Hey the G400 run allot cooler that other card that I had in the past to begin with.

[Brian R.]

Other than there is a fan, a heatsink, and the name Card Cooler, there is no relationship between a dedicated fan/heatsink combination with a shroud and bonded fins, and a "Card Cooler" blowing air in the general direction of a heatsink which may be only getting a small amount of airflow from the fans. Heatsinks depend totally on airflow and are greatly improved in efficiency if they have a dedicated fan. The airflow through a heatsink near a "Card Cooler" is seriously dependent on where the heatsink is in the Card Cooler's fan's airflow pattern. The "Card Cooler" is most efficienct at blowing cool air between cards to feed relatively cool air to a dedicated heatsink/fan combination.

[DuRaNgO]

Hmmm,
install a "blo-hole" in the side of the case with a case fan pumping air to the "card cooler" which in turn pumps the air to the cache heatsinks and the "Lasagna BGA" then is exhausted out the rear through the "Super slot cooler" leaving the need for a bigger power supply...DOH!
maybe I will get the "card cooler'

"32 lbs. of fans, heatsinks and aluminum ductwork"?

[LAMFDTK]

""Card Cooler" blowing air in the general direction of a heatsink which may be only getting a small amount of airflow from the fans"

Brian, small amount of air? you have never seen a Card Cooler have you?

THe Blow holes on th side of a case are real easy to make. you can use a 6x9 speaker grill with an air conditioner filter, you know the black stuff. Its a cool solution.

[ALBPM]

Here's some pics of my homemade card cooler. It consists of two 80mm and one 92mm fans and helps cool the P3 also.




And here's a pic of the 6" X 9" speaker grill which is lined with air conditioner foam filter material.
