P 3 650 OC questions

[ronein]

Details:

Slot 1 P3 650 runs ok at 133FSB using retail HSF at default voltage. Temps are 31C for the MBM and 30-32C via BIOS readings for the CPU. Im achieving this temps with the slide out case removed and with a huge power supply Fan blowing down directly to the CPU. Strange as it may seem its always like this (usually the CPU temp is higher than the sysytem temp); the CPU temp increases if i close up the case. Anyway Im running this thing with the slide out case removed. Anyway i tried to check stability by running seti and prime95 together at the same time and cant seem to make it run stable (computer reboots randomly). I bump up the voltage until 1.8 volts and no improvement still. I try to make prime95 and seti individually and still same thing. Im thinking of removing the retail HSF and putting on a globalwin VOS 32 or some other fancy slot cooler, but with the temperatures im getting with the retail HSF(which isnt that hot, i think), will it make any difference?

Also forgot to mention that i ran prime95 and seti at 126 fsb at 1.75 volts and it ran ok for 5 hours.
Peripheral problems are ruled out because the p3 450 that this chip replaced ran 133 without any problems.

Questions:
1. Do you think changing the retail HSF will make a big improvement on the stability of the chip at 133?
2. Whats the safest voltage you would bump the vcore?
3. Can someone send me a link or give me the instyructions on how to remove the retails HSF?

1. My impression is that switching to a big HSF like an Alpha may make an improvement, but not a "big" one.

2. Max 15% increase from stock.

3. Check articles at THETECHZONE.COM for articles on how to open the SECC2 case. Basically, you put a small screw, like from your case, upside down on a desktop, then put the SECC2 cartridge on top of it, lining up the screw with the pins that hold the HSF in place. Then press very firmly down on the case untill the pins pop loose. Doing this repeatedly on the various pins will loosen all the pins so the asssembly comes apart. You'll probably find that this takes a little courage at first, but it does work.
