DFI NF4 Ultra-D Chipset heatsink mod

[Mastakilla]

Hi all

ive been planning to replace the heatsink/fan combination of my NF4 Ultra-D for awhile now

and finally i did it!!

first i bought an old swiftech heatsink


after this i did ALOT of fitting and measuring

then i drilled the 2 holes

as u can see above, the drill just pushed the pins in the neighbourhood away, i didnt even have to remove those pins

after that i drilled a bit from the bottom away so that some obstructions on the mobo are avoided

as u can see its all a bit amaturistic, but i dont give a about the looks, as long as its silent and cool!
i also used a drill only for it, which is actually a wrong tool :p but i couldnt find any better (and it actually worked )

the next few hours i spend lapping the heatsink... i started with 120, followed by 180, 240, 400, 600 and finally 1200 (i couldnt find any steps in between)

then i went fitting again, and i noticed two more obstructions had to be avoided


this is how it looks like after the lapping and after making place for those 2 extra obstructions (did those 2 with a metal saw, and with a big bolt )


now the heatsink fitted the mobo!!
so i started fitting the videocard... offcourse i had to remove some pins for that... this is the result


then i finally installed the heatsink very carefully with some as5

and after that also the videocard


after this i was very glad everything still worked


and also the results are very nice!!

without any casefans on the temp became 50°C, which is about the same temp as before with that small fan!!
with the casefans on it only becomes around 40°C!!

this is passive!! quite a nice result if u ask me...

Good job but it is much easier to use, for example, zalman passive heatsink. With some good airflow my temps never went above 45C.

I got the idea from this (I had similar setup):

and that is EXACTLY the reason i didnt want that zalman heatsink

i dont wanne be dependant from good airflow...

in the future i wanne install watercooling and bring all my allready slow 120mm fans to 7v if possible
im quite sure that wouldnt be possible if i would have installed that small zalman heatsink

but i know that that zalman is a possible, and easier solution, its just not what i want

Nice work Those temps look like it was well worth the work.

I did a similair mod..

What kind of temps did you get waus-mod?

I decided to run the gfx card in slot 2 @ 8x and use a Zalman without mod.

There is virtually no performance hit running @ 8x compared to 16x

I just ground a small bit of the base of a Iceberq 4 away and I got ~ 45*C temps.
