Gigabyte DS4 has practically identical TIMs on NB/SB and the fets as Afi's Asus.Quote:

Yes, it is worth it. Unless you got tons of highend mobo on disposal like world record breakers coolaler. :D
Do you notice lot of fried mosfets recently like FoxConn mobo ? :)
Got a friend which an electronic engineer which specialized in switching power circuit told me those Mosfet will be poorly perform if they get hotter compared to say when they're cold.
Easy, just equipped with stupid DMM while the mobo on the bench (not in case) and measure the Vcore while using hair dryer with hot air blowing on those mosfets plus running Othos for at least 1 or 2 hours !
Been there & done that, could even reach 0.2 Volt droop on very hot condition.
thx for vdroop mod...modding it tonight :D
Yea, i popped my NB heatsink out too yesterday and i saw about same amount of thermal grease top of my NB chipset what had contact to Heatsink.
Vdroop mod is one thing, cooling those mosfets is also important if you will using the rig for daily use.
Those mod is only modify the voltage sense resistor divider to "fool" or adjust the output to the desired voltage level.
Once adjusted on cold period, it will be shifted downward again a.k.a. Vdroop if those mosfets begin to heat up.
can you do the vdroop mod with pencil, really? if it wasnt to your liking, you could always ERASE it hahahah
but yeah
i wanted to do teh vdroop mod
but i dont want to obviously destroy any warranty/resale value like that
Those MOSFETs might get hot, but do they reach a critical temp for those MOSFET types? Look, what Asus did:Quote:

If Asus would think, that those MOSFETs need a cooling, why should they risk, that one half of the MOSFETs will fail and and that those boards will return on warranty?
Dat Ei
The contact between the heatsink and the northbridge on my DQ6 is fine. Some of the MOSFETS make contact, some don't -I don't think it's important though, since it's 12 phase. Southbridge was terrible, but it doesn't get warm anyway.Quote:

Mine look like this:

See the difference? Mine are lines up in such a way that the Mosfet HS will cover overtop all of them leaving nothing exposed.

As you can see they are all covered.
It appears this is a manufacture issue, not sure if they forgot or were forced to face them that way do to tracing but it's an issue none the less and you need to take to Asus. I am sure a MB revision is in order here.
It's not a defect. You have the P5W DH, and he (as well as I) have the P5B-Deluxe. Sucks about the layout differences, but talking to Asus won't help :(
Its bound to happen with a high selling mobo. Thats probly why some boardscan do high FSB out of the box and some don't.
For phase, this what I did to P5W-DH with liquid tape and rubber band and it still alive:D

So has anyone actually gone ahead and put ramsinks on their mosfets? :confused:
My board should be here by next Thursday so I am trying to decide if I should order up some BGA ramsinks as well?
I pulled out my mobo today because I wanted to do a few things. When it was running I noticed that the area around the NB was rather hot. Everything on my board is stock...nothing has been OC'd or modded. The boards been on for 2 days now. My NB heatsink has the EXACT same contact patch as the original poster. I mean EXACTLY the same. I don't think it was a 1 mistake thing. I think there manucaturing process on these is off. Thats the only way I can see mine and the OP's looking IDENTICAL!
Anyway I'm not sure what to do now. I'm probably going to bend this pipe slightly to get better contact but I'm curious as to what the final conclusion is on this issue. Do the mosfets need cooling or not? Can I just get a different NB heatsink and do away with the whole assembly?
I would just ditch the stock cooling on the northbridge and go wth an aftermarket solution. You can also get aftermarket chipsinks made by microcool which are specifically designed to cool the smaller mosfets. But, alternatively, you could just cut the heatpipe from the northbridge heatsink to the mosfet heatsink and that would probably let the northbridge sink flatten out naturally.
this is enough for dry ice with good pot insulation ;)Quote:

i just removed my p5b dlx heatpipe and yes the contact was terrible. then i messed up with the heatsink and have to put artic ceramique on the nb to replace the original TIM.. rite now my OC stability become worse but system temp is same like before.. :(
I didn't know the temp sensors could go that low. That's freakin insane.Quote:

i notice my NB HS was sitting on a bit of an angle.........i guess mine will be like yours AFI :( but it may require a bit of bending on the heatpipe to get it straight donno if that's a good idea
wonder why board is less stable with a change of TIM?!?
i think i know what to do....................put a couple of rings to tighten the pressure at the bottom of the mobo
looks like that's what you've done there as well hey

How many times has a video card manufacturer put an aluminium heatsink on a gpu and then painted it copper colour :rolleyes: How many times have they then failed to attach this lightweight heatsink to the gpu properly :rolleyes:
Now the motherboard manufacturers are doing the same thing, glitzy copper coloured heatpiped rubbish. I bet it's a piece of aluminium coloured tat that was placed on the board with all the care that 1.5 seconds allows ;)

yeah, you're right, i always checked the area, thats important.Quote:

i ordered jing ting force take chipset cooler but i just realized this board has wifi card beside the nb! do u guys think this wifi card can be removed?
I just checked the NB heatsink on my P5B Deluxe and while it wasn't quite as bad as the original poster's, it was only contacting maybe 50% of the die.
I removed the stock thermal pad and bent the heat-pipe slightly before applying some paste and re-assembling.
It will probably suffice for now, but I think I'll replace it with an after market NB cooler in the near future. Anyone got any suggestions as to which NB cooler to look for?
