Getting my C2 633@950 higher

[Neo_Cloud_99]

Ok I'll tell you guys what I have so far and maybe you guys can come up with some cheap inexpensive tricks, but any advice would be great.
MBD: ASUS CUSL2 - CPU: Celeron 633 - Mid Tower Case - 10 fans specs and position:
1 85 CFM in bottom front blowing in, 1 85 CFM at top for exhaust, 2 30 CFM bottom blowing straight up, 2 30 CFM back for exhaust, generic HSF on cpu, 1 20 CFM on side panel blowing down at cpu, 1 20 CFM in 5.25 bay facing diagonal down towards CPU, 1 10 CFM on North Bridge Controller with a heat sink on it (Just in case)
I have a 300 Watt Antec PSU, and currently my voltage is at 1.85. I can get the system to boot at 969, 978, 988, 997, 1007, all of them make it to the desktop, but they are not stable and crash, and most of them need to be voltage at 1.9 to make it to desktop. I'm looking for ideas besides better fans and besides getting Artic Silver 2, I know of those two? I kinda doubt I can improve on the situation much, but any help would be appreciated, thanks! Thanks for reading it all!

Lapping the heatsink can drop tempratures slightly, and so can improving airflow around your case by doing such things as rounding drive ribbon cables

Well, what is lapping? lol
And, I know its the ghetto thing to do, but I wrapped all the wires in duct tape, except for the IDE ribbons of course, as they are tucked away in drive bays. but... what is lapping?

Is what you do with wet/dry Sandpaper (grain 600, 1200 & 2000) and your Hsf, so the surface in contact with the Cpu is more smooth.

I suggest you to use a piece of glass to work on, it's the surface more flat possible, and fix on it a sheet of sandpaper with tape.
Now you can lap your hsf starting with grit 600, after a while 1200 and at the end 2000 for the final touch.

I hope this desciption help's you.

Be patient for my English :-)

The Doors is right, cept I'd use 220 to start........you may find it's a little warped, and 220 will help you get it flat much faster.

I use my kitchen counter to lap my sinks. I also use 220 to start........300........400........600.......800.. .....1000.......and finish with 1500 or 2000. Using several steps will make it easier and not wear you out as fast. This can esentially take your CPU temps down 10 degrees F. Use a better thermal paste than the stock pad it comes with. Radio Shack sells thermal grease for around $2 a tube, and even better, Artic Silver is about $8.

Also, rounding or splicing your IDE cables helps if they obstruct air flow in any way.
