as topic...i duno those 2 coolers will make a good partner...i see the ttbt vx is very big in term of size...i duno can fit wit hr05/sli or not on ds3 board....

gip me some comment...if cant fit den im gonna get scythe ninja plus and hr05
prefer ttbt vx coz the fan face side when look from the acrylic side panel (nicer)
ninja 1 hav to put the fan side of the sinks...not so cool when u look from side

TT Big Thyphoon VX and Scythe Ninja are those fat fat heatsink...

Yes, they do work well...
But, if u're going to use those heatsink with HR-05 northbridge heatsink, u might have a clearance problem...

Let's discuss...
As u're going to use it on DS3, it's on LGA775 platform...

LGA775 Platform have one good point though...
It is, you can fit you're heatsink on any way you've wanted...

And for that reason, i suggest you get a heatsink with thin thin body...

Such as Thermalright Ultra 120 & Thermalright HR-01 or CoolerMaster Hyper LX

Those are good good heatsink...
Infact, HR-01 are known for it's performance that is on par with Scythe Ninja on fanless...

Dunno about Coolermaster Hyper LX though...

As u're going to use HR-05 on the northbridge, i suggest you take either this two heatsink:

Thermalright HR-01
Or
Thermalright Ultra 120...

[Don't blame me for being a fanatic on thermalright guys ]

This two heatsink are thin and can be mounted on any way...
Either to make the fan go straight to the rear exhaust fan, or to blow it straight to PSU...

You could use you're own imagination...

This way, you could deal with the clearance problem of using that HR-05 with those fat fat heatsink...

So go get you'reself those thin thin but high heatsinks...

Spacing of the 965 boards are inherently similar to the old 865 boards.
I can fit a Ninja and HR-05 on my old P4P800 and I believe it's applicable to the new 965 mobos as well. So I believe you should be fine with the HR-05.
