Abbreviated subject matter at the bottom.

I was just wondering how many people if any are fond of the idea of planeing chipsets ? I got soo sick and tired of the audio issue with my NF7-S 's overheating SB that I put an active cooler on it. . . nothing. After a month of still getting sick and tired of the crackling ( though longer into gaming ) I removed the HFS that was attached with some thermal tape, Lo and BEHOLD !!! Only the corners had been making contact. Being the problem solver I am I got a bright idea. "I'ma show that soab SB, I'ma plane your adz now beoch!!" . So I did. I planed it till the Thermal tape was not making contact with just the edges or inside, I now get an almost perfect fit : ) And I cranked the baby up, fired up CnC Generals Zero Hour : ShockWave ( BETS MOD EVER !!!! ). Now ( drumroll please ) no more crackling sound : )

Planeing my SB has seemed to work perfectly for me, anyone else done this or know how good of an idea it would be for a NB chipset ? If it worked for my SB issue then following the same train of thought it should work for my NB as long as I don't remove too much material from the chipset.

Abbreviated subject matter :

1. Is planeing ( making a surface level ) a good idea for chipsets ?

2. I had a SB heat related issues with my mobo and planed the SB, now the issue is gone.

3. Is planeing a good idea for NB chipsets ?
 
I've honestly never attempted it...I've lapped many IHS's and heatsinks...but if you're carefull enough it SHOULD work. Not sure what kind of leeway you have with a NB when you're sanding it down, but hopefully someone around here has given it a shot and can chime in.
 
I've lapped the lazer etching off of an old duron processor. I gained 1'c. It was a bad idea.

You're saying you lapped the actual DIE of the SB chip? I can't imagine a company would let such a small chip leave the factory not flat. Especially because the manufacturing methods almost ensure perfect flatness! How much silicon did you take off? Are you noticing any wierd things happening, like, a loss of IDE drives or something :D.

Tell me mooore.
 
Guy above me : Yes, I planed the SB ( MCP-T South Bridge chip ) itself. It no longer says MCP-T on it :D

I've suffered no adverse side effects. My optical drive is still registering as well as all of my input devices and my Pci card. My Silicone raid chip handles my drives so thats no problem. I took prob less than 1/3 mm off the SB but it was enough to make the SB almost perfectly flat. The SB is the MCP-T SoundSorm enabled one. And for the guy above the SB was not completely flat, no company ever put a cooler on the SB chipsets so I'm assuming it was never taken into mind that it should be flat.

Like I said previously. Since I planed it my crackling sound issue has dissapeared :D I don't see how planeing the MCP-T SB can be a bad thing if you don't take too much material off. I'm not sure about other SB's or any NB at all.
 
Awe man. You're running a socket A processor ;). The SB on that board doesn't even come with a heatsink haha, I should have checked that. I was worried for a minute.

Those "metal label" capped chips get really, really hot (A laptop of mine gets to almost 60c!). Lapping those bad boys isn't anywhere near as scary as lapping a bare silicon die version, so what you did was actually a really good idea.

With older boards that have been handled alot, sometimes a 99% alcohol bath will get rid of wierd onboard sound noises. Traces of oil, metal particles, dust etc can change the electronic properties of PCBs quite easily. I've been able to overclock my GPU an extra 17mhz after bathing it (I use it for testing alot, so it gets handled daily). Just another one of those wierd tech mysteries I guess.
 
I have always lapped my NB's/chipsets. They are concave - all of 'em. It's easy and safe if you know what you're doing. It also makes a HUGE difference in contact.

DO IT. :)

I just "planed" my brand new DS3's SB and man it needed it. It's perfectly flat now .

I'm not so sure I would trust you. you sound too... hmm... happy about it...
 
not to hijack your thread... well maybe a little bit... should I plane my old celerons? I have 10 of em laying around. they have a metal casing over the core, and I never have looked to see how flat they are.
 
I suppose LAP would be the correct term... I guess I'll have to scrape the 5 year old gunk (used to be thermal paste) off of them...

Hahaha! That's funny. Bro I've been OCing since the Pentium 2 days...I had water when water was just coming out - well before "kits."

"Back in my day, we didn't have WC kits! We had to hike to Home Depot in 6 feet of snow uphill to buy our fountain water pumps and tubing!"

heh.. no offence, you just sounded too happy about it to be surios. (I figured sarcasm)
I dont trust happy people LoL (I work with family if that explains it)

I remember those days... I had considered WC at the time (on my dual celerons) but didnt find it to be worth it... now however, I'm looking into it...
 
Okay. I planed my NB and while I was at it lapped my NB hsf and my Volcano 12 ( I know that shoulda been done ages ago but eh. ) .

So far I haven't noticed any increased stability with my 250x9 OC ( was unstable before and still is atm ) . Gonna change a few more settings arround for the next day or 2 and will let you guys know if it did anything or if its not worth the risk.
 
What's your NB voltage at? NF2 chipsets take a fair bit of work to hit 250MHz.

All NF2 chipsets are concave, noticeably concave. Flattening them takes a while, but the effort pays off. I did it to my old Asus A7N8X-X, and I've done it to my current DFI NF2 Ultra Infinity. It sucks pulling off the NB heatsink and seeing that your nice layer of AS5 only touched the heatsink on the tips of the corners. :D

Doesn't really surprise me that it might not have helped...typically you'll need more then a lapped NB to hit 250fsb stable on a lot of NF2 boards.

Good luck though, keep us informed.
