Yea it makes sense... I was thinking the same thing... about whether its worth or not. It could go worse than the current one. Most likely it will... cos lapping will still change the surface (permukaan) right?

Yup!
Consider what you're getting now is good la bro...

I'm afraid if it would go worse...

a lot of people seem to vote to lap the heatsink again... I wonder why... can you guys gimme ur reasons?

@J-Slade

They just voted it maybe coz they are not the one who lapped it

I thought so too.... prolly most of them (maybe all) have not even tried lapping a heatsink

Oh... the horror

Well, some people are paying money to get a drop. So y wont u lap again, since it's free but just needs some time?

its not free since my tube of Arctic Silver 5 is finishing.

Hmmm lets see, firstly I'd have to take it out which is very troublesome. I tried once... seems like the XP-90 (which is very tightly stuck to the CPU due to its 'retention' design) got stuck to the IHS which made the CPU once got totally plugged outta my socket despite its locking

Hmm.. lets see, 2ndly... I have lapped it to 2000 grit paper which gave an almost mirror shine (still very rough.. not totally mirror yet) and I supposed that could already be the max I can do. Unless I find a very flat piece of glass which will of course allow me to lap properly further.... but so far, what I have is only a loose tile from my kitchen. I dunno how flat it is but it looks pretty ok to me....

Thirdly... hmmm lets see.... its just abt this whole lapping process. I kinda feel that it might not be as 'very' much effective as it is supposed to be... sigh i dunno man... kinda lost now. I feel like giving it another try

probbably coz everyone is curious to know how much more u can squeeze out of the hs haha...also guilty here as charged ...anyway u might as well coz if not you'll always be wondering shud i or shud'nt i for as long as ur using the hs...right?

you're right..... i hate joo

haha....know why...coz we're all humans...seriously tho, pls dont forget to post the results...wanna see how much u can squeeze out of that "fella"

forgot to add... maybe u like to take pix of ur progress...sort of before n after...n post it here, also great for ur pix collection...anyway always great to see pix like that

so have u made ur decision yet???

ur rite, agree with u

Yes I have.... check out the first post guys

Btw, thank you all for voting. It seems that the result is almost becoming a tie

just to repeat what u quoted:

"Nice.... nice..... very nice" ,

glad it turned out ok...anyway got 2 questions:

1) cant afford arctic clean, but can afford Sony cam....

2) got time to lap another hs?

1) My dad punya la... for some reason, he's into brand names. When in actual fact, Sony is just all name no performance...

2) Haha... want me to lap for you? Can... but no kick la... you gotta lap then you feel the satisfaction of the hard work.

haha, ya think i'll lap it when the time comes to take the hs out....anyway abt the sony cam...not too bad actually...the ccd n lens are abv average frm personal observation/comparison.

so far any difference before and after lapping ??

kind of curious coz usually lapping results few degree drop at least ...

does AS5 need 200 hours to get sink ?? i noticed around 3 days will do ....

of course i might be wrong as well...

Urm... okay, first time I lap I managed to cool down by 2°C. After allowing AS5 to sink in, got another 2°C.

Now second time with proper lapping and much 'cleaner' shine, the temperature remains the same as before (dropped 4°C) but not yet sink in so I am expecting another 2°C drop...

means... my total effort in lapping heatsink (with quality AS5 thermal paste) should be around 6°C... but who knows, I might get better results. Will update it in a week's time.


*update*

I just tested my Prime95... got a noticeable 2°C drop from before.....

great result from your great effort..

great, so the lapping really drop 2 degrees

Thank you so much

Yes, it really did drop by 2°C........ better than 1°C

Anyway peeps, this is out of topic but before I threw away the trashed up sandpaper, I managed to lap one more heatsink for today...



Tadaaa~
My old skool socket 754 AMD stock heatsink. Yea I'm not gonna use it but oh well, since I had extra sandpaper might as well not let it go to waste.
