ASUS P5W DH - Problems + Fixes Thread

[cbell]

Can anyone recommend a good heatsink to replace the stock one on the NB of the DH Deluxe? I'm using a Big Typhoon for my CPU, and it has pretty good clearance. I don't need anything too amazing, just wanna be able to raise the vMCH a little without having to worry about it.

I like the Zalman ZM-NBF47, but I'm not sure if it will properly mount on my board, or if it will even make a significant improvement over the stock HS.

Also, can I simply cut the heatpipe that goes from the stock HS to the HS on top of the MOSFETs? Or is there some more elaborate way that I need to separate them?

I'm using the Thermaltake Extreme Spirit II as suggested by Lawrywild.

I tried the Thermalright HR-05, which is a superior heatsink, but the retaining bracket provided isn't suitable for this board.

Note that the Thermaltake Extreme Spirit II isn't really suitable for the SB if you're considering that - I found that the retaining screws were too high and prevented correct seating of the graphics card. HR-05 SLi works fine though (excessive for the SB i know...).

I think that my s. bridge is overheating, I've used some very complicated high-tech equipment (my finger), to measure the temp of the heat sink, and I've found that it's untouchable. Though, I can't find any software that measures the temp of the s. bridge. Does anyone know of one (that is preferably free)?

I need to be sure that it's overheating before I send it back because I've only had the board for two days and had to buy XP for it. If I get a replacement then I get to buy a new XP license. *yay*

SpeedFan 4.32 reports a number of temps from all the chips/sensors that it is able to read. On this board, it shows 3 temp readings from the Winbond W83627DHG chip, namely CPU, AUX and System.

Now, I could be totally wrong here, but I sort of assumed that the System temp referred to the SB.

I have noticed that the AUX sensor temp increases under load, whilst the System temp remains stable. That made me think that the AUX sensor was maybe the NB, and the System the SB.

I'm happy to be corrected if my assumptions are incorrect...

I don't believe that is correct. The temp reading for the system is low, no where near the temp of the heat sink.

FYI:
- System/Motherboard temp sensor is NOT inside either of the bridges:

I love this thread... responses are fast and it fills up with new information so quickly.

Thanks, I'll try this for my NB. I'm not overly concerned about my SB; I replaced the thermalpaste with AS5 and took off that weird metal cover over the heatsink.

It is as simple as cutting the heatpipe. There should be a small amount of liquid in the pipes (most likely water), but nothing to worry about.

Better way is too place the chipset cooling assembly onto stove burner @ 75% heat for about 10 minutes. While hot, gently twist the mosfet part and it should come loose from heatpipe. then you are left with empty mosfet cooler, and intact heatpipe, should you decide to restore stock cooling!

Thanks, sounds easy enough. Would you guys recommend that I upgrade my cooling if I only plan on upping the vMCH to 1.65? Or would stock cooling with AS5 be sufficient? I have my overclock turned off for the summer, so I'm planning ahead for fall right now.

I tried the Thermalright HR-05, which is a superior heatsink, but the retaining bracket provided isn't suitable for this board.

I'm surprised nobody responded before now to your many posts about mounting the HR-05 on the north bridge.

It's actually fairly simple: after removing the stock NB heat sink, pry its clip from the HS (it's held in place with friction by some folded metal), then use that clip on the HR-05.

Or, you can do what I did before realizing this trick: bend the s**t out of the supplied HR-05 clip so it slips under the hoops of the P5W, which are of course on the opposite corners to what Thermalright designed for...

I asked the same question a couple of weeks ago

The inside of the pipes also contained a copper-coloured crystalline solid - not sure what it was (more copper maybe?). In order to avoid the risk of anything dropping onto the board from inside the pipe after installation, I chose to remount the MOSFET heatsink the opposite way round, so that the open ends were facing up (tower case).

Anyone able to flash back to a older bios, I experimented with bios 2004and I want to switch back to 1601 (unlocked multi) and everytime I try to flash back, it says older bios detected, please download latest file from ASUS website.

HALP!

You, my friend, must flash using a floppy, and afudos. using the proper switches, you can force the flash.

Telling me the switches would be helpfull,

What I've used so far Afudos /iP5WDH.Rom /pbnc /n and still won't work, yes, I renamed my Bios to P5WDH just to try the Alt + f2 Flashing.
