NB/SB Cooling for Noobs?

[bobross419]

I've got an Asrock 775Dual-VSTA and I'd like some basic information on cooling the NB and SB. My work is junking some older Dell models and I salvaged some coolers. They just look like a mountain range, maybe 1 1/2" on a side and an inch tall, all of the spikes are the same height. I couldn't find a picture of this and I don't have a camera :

I've also grabbed a few small fans.

What would be the appropriate method of setting up a North bridge or south bridge heatsink? How do I figure out what my north bridge and south bridge are?

One other question...

In HWMonitor I get a Temp1 and Temp0, how do I know which is the one that I'm supposed to look at for my CPU? Temp0 hits ~70C with a mild overclock on stock Intel cooler with a Pentium D 930.

Thanks

No answers yet? OK, no one else is willing, I won't leave you hanging.
Is this your board? The silver colored heatsink is on the NB, I generally find mounting a 40mm fan on this is sufficient. You can use "Plumbers Goop", a couple of really small dabs on the motor side will stick it to the sink. Your SB is the chip marked "via" (V/A) in front of the battery and behind the drive headers. For this a low profile heatsink is generally used so you don't have conflicts w/ pci cards, looks like a 30 x 30 x10 mm is about what you need. What are you using for the cpu heatsink?
I don't use it but if you post a screen shot of hardware monitor maybe I can help you decipher the temps, have CPUz running and in the screenie too. Google and download if you need to.

If you have the manual most of the parts on your mobo should be identified.

The chip on the Dual VSTA with the existing HS also has the video in it. If there are no holes around the other chip, then you'd have to use some type of adhesive to hold a HS on it. There are double sided thermal tapes and glues. I'd avoid anything that wasn't easily reversible if I was doing it. Zalman makes a nice selection of heatsinks and you may get some ideas from their site.

Beside Zalman, Enzotech make some nice passive coolers.

I am not a fan of 40mm fans Way tooo loud for my liking.

If you can get a nice 80mm Noctua...you will get cool and quiet.

Crap, I forgot to subscribe and totally forgot about this thread Sorry it has taken me so long to respond.

My CPU HSF is the one that came with a Pentium 4 520... it can be seen in this picture:

(That board is actually mine and they are using a Pentium 4 524 =p )

I have a few of the little Foxconn North/South (Not sure which) heatsinks from an Optiplex GX60. It is 3.75w x 3.6l x 2.3h (cm). It is a crappy picture, but the only one I could find:

This is the black, spikey heatsink that you can see in the top center of the top left section of that pic.

I'd like to be able to glue it on somehow. One of my coworkers suggested a thin layer of epoxy around the outside edge, then thermal paste in the middle... would that work?


I'm at work right now, but I'll try to get some screenshots of HWMonitor over the long weekend and post them up.

Thanks for those links, both products look really good... does anyone have any experience with either of these or both?

The warning on the Arctic Thermal Paste about components staying connected forever does worry me a little.

Both, what your co-worker suggested works with that paste on a large surface, 1" square like many SB chips, a dab at the corners and the grease spread elsewhere. I use the tape on memory chips and v-regs that have a small surface area and a small sink. NB almost always have a mechanical fastening of one sort or another.

Awesome, thanks for the tips
