DFI ultra-d SLI moded chipset solution

[AlanD911]

I previously moded a vantec iceberg 4 pro chipset fan for my DFI ultra-d, and after adjusting the fan in the bios to turn on full at 25 degrees my temperatures are staying at 45 degrees on the chipset at load. The clearance is perfect for an SLI setup.. There is a guide on how to do this at this link

Tools needed:

drill

1/8 drill bit

dremel with grinding bit

alittle bit of time

 

This temperature seems high, but keep in mind that this is on a dfi ultra-d with a 3200+ winchester overclocked to 2.6 ghz running with a 1.6 cpu voltage along with 2x 6600gts running at 500 mhz and 4x 512 PQI TCCD dual channel sticks.

So how was your temps before the mod? I was going to purchase the Evercool VC-RE instead. One thing that does come to my attention is that the stock chipset fan has some sort of padding for the areas around the chipset core that should be needed for aftermark fans or not? So your chipset fan is running at full speed from 25c and at load its still hitting 45c? What's the temp in your room and your case air circulation?

My temps before the mod were high 40s when overclocked to 2.4, now they are only at 45 load on the chipset with the cpu overclocked to 2.6 with 1.6 voltage to it. You dont need to have that padding on the aftermarket vantec iceberg 4, I have heard that the only purpose for that padding is for the cooler not to tilt, but this doesn't seem to be a problem. My chipset fan is running at full speed which is around 5000 rpm or so and it still hitting 45. The temp in my room is around 23 degrees celcius which is 74 degrees farenheight. My case cooling is as follows 2x 120mm panaflo low fans (around 60cfm each) for intake and 2x 120mm silverstone speed adjustable fans (max cfm = 100 or so) as blowholes on the top of the case. Right now I have the silverstone fans at the lowest speed setting so i'm guessing I get maybe 20-30cfm maybe , not sure since they're on a fan controller.

One thing you have to note about using the vantec iceberg 4 pro is that you need to have some kind of grinding device such as a dremel in order to make notches in the chipset cooler. The fan is so big that it goes over afew pieces on your motherboard and does not sit flat without some grinding down in 2 areas. For furthar information on where you have to grind check out the link in my previous post.
