i have the old thermalright SK6 pure copper cooler with a 5200rpm thermaltake fan running on my tbird 1.4
now, im putting a new xp2400 into my system today, and it came with the OEM aluminum and what not HSF setup.

being that this oem HSF is newer AND designed for the new tbred, would it be a better choice using it over the SK6?

opinions plz
 
i got an Sk7 with a 60 mm YS TECH fan at 5v and it gets 120F max, stock 2400+ mobile. very quiet but not the greatest temps, then again craptacular fan.

Kust watch the mating surface of the stock cooler and the thermal material, my stock cooler was an extruded nightmare, the base was like 200 grit sandpaper, I had to lap it, I also used arctice ceramique...works like a charm...

You could try both..and give us an informal review...Remeber the vcore on the older cpu was higher than the newer cpu so the older cpu should run hotter than the new cpu with a lower vcore.

the SK-6 is a pretty dinky ass heatsink.. With that fast fan and lots of noise (60mm, remember) it will probably cool slightly better than the retail cooler. But i think for the same noise level you'll probably get better cooling from the retail. Just my guess.
 
well this is my take on it thus far
the OEM heatsink is slightly larger then the sk6
the sk6 however, is noticably heavier as it is pure copper, opposed to mostly aluminum
the oem fan runs at 3200 rpm and is smaller then the one i have on the sk6. the sk6 fan i have is running at 5400rpm
the OEM HSF is quieter

i couldnt find any thermal grease yesterday, so i couldnt install the sk6 just yet to see the temperature differences, i will have a better answer later today
 
SiNiSTeR_MoTiVeZ, I'd like to hear your updates on this - I'm in a similar situation, I have an xp2700 with stock hsf and I have an old sk6 laying around from my 1.4 thunderbird so I would be curious to hear how this works (of course I'm really going for quite so I'm not sure that my jerry rigged sk6 with quiet 80mm panaflo strapped to it would do any better then the stock cooler - opions?)
edit again, more I think about it the more I think that maybe the sk6 with an 80mm quiet panaflo might not be such a bad idea, I'm just having a hard time finding out what kind of cfm the stock amd fan puts out so that I could compare, does anyone know/have an estimate?
thanks much.

--ok another edit to boot: does anyone know of a 60mm to 80mm fan adapter that works with the sk6? I know that you can rotate the fan 45 degrees and get it to fit but that really seems inefficient to me--. Thanks much.
 
ok well i mounted my sk6 with a thermaltake 60mm 5400rpm fan
idle temp is much cooler, it sits at 36c now, opposed to 44c on the OEM hsf
unfortunatley i never took any readings under load with the OEM hsf, so i cannot compare there

i think by using a bigger fan, it would improve cooling even more on the sk6
i personnaly want to buy this
and see if i can mount it somehow on the heatsink, otherwise i will just use a standard 60 - 80mm fan adaptor
 
SiNiSTeR_MoTiVeZ, I was also thinking about that hsf "duct" as well but I just couldn't see any way of mounting the thing on the sk6 but then again, the same goes for other 60->80 ducts. Let me know if you have any success with any adapters/the thermaltake "duct" I'd be very interested!
thanks again for posting your results. (I'm still trying to figure out what the cfm on the stock amd fan is so I can see if my super quiet panaflo will move at least the same amount of air - going for silence rather then huge cfm).

--edit: found some reviews of the thermaltake "duct" that didn't exactly praise it, mounting on the sk-6 also sounds rather difficult, involving self-tapping screws into the fins of the heatsink & etc., anyone have any suggestions for a fan adapter for the sk-6 or is my current method of just having the 80mm turned 45deg acceptable?--
 
If you choose to use the sk6, then make sure your use it with a good fan. The OEM HSF that came with the 2400+, are really not that good. They did not start improving until the late 2500+ and above...
 
darktiger,
thanks for the input, any knowledge of the stock hsf setup for a retail xp2700? I havne't been able to dig up any information on that hsf assembly to see whether or not my setup would benefit from an sk-6 with 80mm panaflo.

NONONONONOOOOOOES! Don't buy that mod, for ~$0.50 (US) you can do the same thing...

THIS guide: http://tweak3d.net/tweak/airflowtweak/5.shtml (found in the Unofficial Official Tweak Guide Thread in G[H]) describes how to do it w/ a two fan heatsink.
you can also just "shroud" the HS w/ masking tape even if you only have one fan; it helps considerably.

essentially what you do is wrap the heatsink in masking tape from the fan on down. This way, whether your HSF is sucking or blowing (this is also covered in the above mentioned guide) it will be pulling/pushing air out of/on to the center of your HSF area, therefore, it will cool the core better, yielding lower temps.

Try it out, and post back w/ your experiences!
