Show off your heatsink

just a question to the people that have water cooling installed on mobos with heatpipes, don't you have to cool the heatpipe heatsinks with a fan after you install water cooling? They are normally cooled by air from the air cooled CPU heatsinks but with water cooling there is no air movement.

they are fine if you have low rpm fans circulating the air

(at least for me)

For me the case fan is not enough even though it's sitting few centimeters behind the heatpipe heatsink. Without additional cooling of the heatpipe my mobo temp goes above 50C but with cooling it stays at 35C.

You can just about make out the heatsink on this one

how do you cool your heatpipe? i have the same motherboard, and the same problem

i find that the supplied cooler is a bit noisy, have you devised another way of cooling the pipe?

Take a closer look at my pic, there used to be a heatpipe on there cooling the mosfets and the Northbridge. Zalman heatsinks are now in place but tbh even they are probably not needed as the top row wasn't even sinked before. Imo the heatpipe thing is simply a gizmo.

Bit wonky, but it'll do.

I finally got round to it, here's mine. Think you can see all 3 sinks from that pic, NB - CPU - GPU.

Is that a Zalman Resorator?

The best cooling of the mobo that I have found is a 6cm fan (from a stock AMD HSF) that I attached on a metal arm and it blows onto the southbridge and PCI area. I run it on 7v so it's inaudible but lowers the mobo temps up to 10C. If I run it at higher volts it's even better but make more noise. There is a pic of it below. I've also attached the supplied blower which is attached to the mofset heatsink and also run it at 7v to make it inaudible.

Mine is yeah

Neither the stock amd fan nor that blower fan are inaudible at any speed, so to suggest that they are is incorrect.
And in my experience neither of them are particularly quiet at any speed either. Also the fan supplied with the amd stock cooler varies between models.

Although i'm not watercooling i made a duct from my rear case fan to the chipset/vreg heatsink and that seems to work ok.

Jfan · 28 Oct 2006 at 00:01

some great ideas thanks, might try a bit of both extra fan and ducting although not much room down there with sli gto's

anyway we better get back on topic, ill post my hs pic when i get a scythe ninja or a tuniq tower next week, just got an artic 64 atm

There is no noise difference with these two fans ON or OFF when I'm siting next to a closed PC case when these fans are at 7v. That's what I call inaudible, if you put your ear next to the fan then you will surely hear it.

I've made an acrylic duct to cool the heatpipe heatsink with the rear fan instead of using the supplied blower. It does a good job but when the rear fan spins at 12v it produces a little bit or resonance so i'm trying to improve it at the moment.

Im currently using a Freezer 64 pro, but will be using the following soon;

Although as you can see, it still needs to be built.

You must have a relatively noisy pc then. To me inaudible means you can't hear it at all, or you can't hear it except if you put your ear to it. If i put that blower fan in my case it would be the nosiest thing in there.

I think i'm going to have to re-do my duct too, as i left the rear fan on very low for a while and something was reporting 57. Its in an annoyingly difficult spot to cool. The top vreg heatsink is easy, i just stuck 3 fans above it with double sided tape.

Day03 · 28 Oct 2006 at 00:33

If you run the blower at 12v it is loud but I'm running mine at 7v. The noisiest parts in my PC are the 3 hard drives which are gel mounted anyway so the fans cannot be very noisy if idle hard drives are noisier.

Joe42 · 28 Oct 2006 at 00:35

Its all subjective i suppose. Currently the noisiest thing in my case is the spinning of one of my disks, the other is in a foam box.

Jfan · 28 Oct 2006 at 00:36

hmm i like that duct you have there day03, think ill have to try something like that

Joe42 · 28 Oct 2006 at 00:42

One thing you have to remember is that that heatsink is also attached to the voltage regulators, and temperatures like 50 are pretty cool for voltage regulators, getting it much lower than that is going to require considerable effort. I imagine the chipset mush have been designed to run at the same sort of high temperatures as the voltage regulators.
