The real question is, is it worth your time and work? <-- This is a real question, bkn sindir.

I think it's more of interest and the joy of modding (lapping)
It's not much of a difference in terms of temps but at least I tried it out and manage to witness myself

Hello can i know what's your rig and idle and load temp?
Mine Brisby X2 4000 Default Volt 2.7Ghz idle at 41 celcius and orthos run at 48-49 Celcius.

too good to be true, only 8c additional in load

Huh izit good?I still thinking shld i change a better thermal paste / lap my HSF = =

My idle is about 25C-27C in an air cond room. If there's no air cond then 32C-33C.

HOW COME ?! I using CM690 and closed casing and One 12inch fan for exhaust and two 12Inch fan for intake.Two 12Inch fan running at 2k RPM blowing my GeminII.How come so far diffrent?

I really need a new heatsink in order to OC my brisbane. OC it to 2.3 n the PC freezed during ProStreet @ 1680x1050. Checked the Asus PC Probe thingy n the tempt was +- 57. Wanted to get this because was excited with the size of the thing,but i realized that it's too big. Want sumthing good and small.

Get xigmatek.Pm ckhoong for more detail.

yeah, me got 29/30C idle and 43/44C load running at 2.9Ghz, also result after lapping...
also agreed with bro clawhammer, lapping is more of interest eventhough only reduce 2-3C, but satisfied lor, result of our own effort
currently using 'cap ayam' thermalpaste, plan to get Tuniq-TX2 after this, maybe can reduce more temp

OMG I'm happy to hear so.Wanna know more bout lapping now.BTW ur casing is closed or open?

what do u mean by closed or openend casing? my casing originally just normal old style casing, i modded its top and side panel by putting acrylic and fan (12cm on side panel as blow in and 8cm on top as blow out, in addition to 8cm blow-out fan at the rear, also made another 1 blow in hole at the front with 12cm fan, total 2x 12cm blow-in, 2x 8cm blow-out), so i guess airflow of my casing is at optimum level already...
everything about lapping i learnt from my friend, which he learnt it from IceMocha's thread, managed to make my gemini's base quite shiny, but still not as good as IceMocha's lor

yp skylineGTR, why not get MX-2? Tuniq is better?

for real, i dun know lor, never use it before, but some reviews say so coz its water content more than MX-2, can preserve its moisture even after few days use (that's what the reviews say la)...

Oh ok There's something new which is made from Diamond dust. Those folks in the US already have them. Hopefully someone would bulk it back here.

waa, diamond dust?? not expensive ka bro?

Fortunately it's not and around the price of AS5. I think they got the dust from those diamond makers because when they cut the diamonds, there'll be dust so they collect them and turn it to thermal compound. Just a guess but I'm really looking forward to it as many people says they give better temps over MX-2 (which is currently the best)

from that reviews, MX-2 is behind TX2 and AS5 la bro, but dun know whether its true or not

I gotta lap it when reach home.BTW what is the first grit u used to lap?Cos i can see the GeminII come with quite smooth surface.Can skip to 1200 grit?

i bought 2nd hand 1, so its base was oxidized already, so i started with 800, if urs still new, i think start with 1000/1200 grit is ok lor
