SKT 478 P4 temps question

[kaos kid]

I have an older very cramped flex-atx shuttle box with a heatpipe type hsf setup. I recently replaced the 2.53Ghz P4 with a 3.06Ghz/512k/533fsb HT P4 cpu, and noticed that at idle the bios shows mid-to-upper 40C temps and under load (one core thread gets up to around 80-90% and the other to around 40%) in mbm5 it gets up to at least 56C and as high as 62C. Is this too hot for a single core HT P4 of this nature? I want to use it for a htpc but I don't want to burn out this chip while watching .mkv files on my LCD. An old review I had found mentioned the 3.06Gh cpu would probably be too much for the hsf that came with his box, but I don't know how hot you can safely let a P4 get. Thanks for any input you can give on this matter...

I have a P4, a 551 3.4 w/hyperthreading I bought in an AOpen book style case. It normally ran in the 50's, not a problem. It will bluescreen and shutdown when it reaches it's threshold before damage. I've had it running on various motherboards overclocked w/ added volage for to 4.0 for about 5 years.
Run prime on it for 15 minutes and it will reach higher temps than any normal work you may task the chip with during day to day usage. If it does not bluescreen and or shutdown after that you'll be fine, if it does get better cooling.

Thanks for the reply. I found an obscure reference on the intel site saying that 69C is its max temp, so hopefully if I can keep it under the low 60's I should be OK. I reseated it with some AS5 I had in the old bin and am going to let it acclimate/cure at idle for today and then try running prime tomorrow. It is currently idle at 46C according to MBM5 so we'll see how that goes. my biggest limitation is air flow room since the drive cage installs over the top of the CPU I only have a smidgen over 2 1/2" to work with.
