Should I lap my HSF and CPU?

So....I have a S1823 HSF...I have noticed that it is not very flat, when I clean the theraml paste off...I always have to use compressed air to blast it out of between the heatpipes. I've never lapped before, let alone sanded anything. I'm thinking I could buy a lapping kit that came with a piece of glass and all the right paper etc....but is it really worth it?
 
It's not that hard, and when I used to OC heavily, lapping could easily bring the temps down 2 to 5 degrees C. And if the heatsink is really warped, it can bring it down even more.
 
Yeah...I think I will. I also noticed some little dents in the heat pipe where the corners of the proc were. :(

Anyone know of a good lapping kit for newbies? Preferably something that is fool-proof with instructions.
 
What's an S1823? Did you mean HDT-S1283?
Got any macro shot pics of the bottom of your HSF?
I don't bother lapping my HSFs because the 2-5°C isn't worth it to me. I just put slightly more TIM instead, lol. Works out well, but then again, I've only had to do it twice.
 
Maybe I will just use so much TIM, that its overflowing onto the mobo. It's non-conductive anyway...am i rite, or am i rite?!

Hey dude, did you get my PM earlier?

On topic:
Yes, lap the HSF. CPU is probably pretty flat, and you will void your warranty.
Start with 200-800 grit and move to 2000 grit. Only use the weight of the HS, no pressure. GL.
 
Is it going to like...be bad if I don't lap it? It's a small gap between the heat pipes and bottom of the heat sink, but big enough to get TIM stuck in it.

Well it's not going to be necessarily bad, but you can lose a few degrees if you do lap it, and it's not hard.
 
As was mentioned, if you're really intent on lapping, lap the HSF first and then give it a try. You don't want to lap your CPU unnecessarily and void the warranty. Depends on whether the 5*C is worth it for you.
 
lapping is incredibly easy... you should be able to pick up the supplies at any local hardware store. there are plenty of guides online
 
Thanks for the link....I guess I will apply paste to the HSF, rather then the cpu using that double line method. :)
 
I would lap it too. I remember lapping used to be more popular back in the Athlon XP days, I haven't heard much talk about it lately. Like the others have said, it's not difficult at all.
