For the lappers out there, do you still use the same method to apply ** artic silver5? i.e. small line down the middle as per ac5 instructions? or does the clingfilm finger/scrape off method work better on a lapped cpu/hs?
Many thanks.
Lapped pics to follow soon...
 
If you have lapped the finger application works well vs the AS method. A small amount of AS grain of rice size spread and use a credit card/ Stanley blade to even off and remove any excess
 
If you have flat surfaces and can do it correctly, nothing beats spreading.

The new AS method is crap and its simply to let n00bs do it as it dont take much effort. (they need cater for all users inc novices not the tech geeks here). ;)

I lost count of how many peep on XS had to do multiple remounts on there Tuniqs (funny it all seems to be Tuniqs) to get decent temps, they all ended up spreading and temps were better.
 
Allways had best results when spreading when lapped. Spreading thinly won't be too good if you have a badly concaved IHS though as there may be a slight gap between the HS and the IHS. Arctic silver. in there defence, can't really cater for all instances, lapped IHS, bowed blocks etc.
 
If you have lapped the IHS wouldn't you need to lap the HSF aswell before using the credit card method?

Theres a good chance the HSF isn't totally flat aswell.

If we are being petty, you should consider using a capital letter at the beginning of a sentance and full stop at the end before correcting someone on their use of the English language.

Check my post.. I started my sentence with a capital letter, and ended it with an exclamation mark. The sentence that did *not* start with capitalisation was...

Part of a quote.
And there's no 'a' in sentence ;)
Failboat ahoy!


..aaaaand back on topic.
 
anyone ever read of anyone going to the extremes of lapping the 2 surfaces so that they can be wrung together ? technically the heat transfer would be perfect with no thermal compound needed wouldn't it ?

I've done just the same, although I'm waiting for my coolant to arrive before I can put them both together. It was much easier than I expected it to be :)

There's no way a home user could get both surfaces totally flat without using some kind of machine to lap both the IHS and HS/F, thermal paste is always a good option, even if it is only the smallest ammount.

But i do see where you are coming from, in theory, if both surfaces were 100% totally flat, then yes, there wouldn't be any need for thermal paste at all.
 
They could get it as flat as flat can be (ever seen a pic of a new Razor blade under a microscope, its like a mountain range).

At work we did machine parts but valves etc are all finished by handtools and Lapping/Grinding Paste, they end up Gas Tight.

I have lapped heatsinks on a 10mm thick piece of very flat glass (you pay extra for it) and then used Engineers Blue/Marking Blue to check for High Spots.

Yup! :)

Blob'n'Go is the best way lol, no condom fingers, no lint free cloth, no credit card, no voodoo! :D

The only trick is to know how much paste to use and that only comes from trial and error.

In the past I have worked up a sweat applying TIM, going at it like a master plasterer trying to get the perfect micron skim finish! :o

Lets not get too anally retentive about this guys, just splodge the right amount of TIM onto the IHS and get the heatsink mounted.
 
I have seen as much as 2c difference from using too much paste. I certainly wouldn't be stupid enough not to use any though. No amount of hand lapping will get the microscopic crevices out that the thermal compound serves to fill.
