Thinner style Pentium IIs in an 1850R

I have acquired two of the thinner style Pentium II/400 processors and swapped them out for the original 'fat' Pentium II that was in my 1850R.

They fitted in fine once I removed the fans, which I figure I don't need as there's a dirty great big fan in the case to keep them cool. Everything boots up OK.

Can anyone tell me if this will place my system at risk? Can the smaller heatsinks keep the processors cool enough in a server?

Re: Thinner style Pentium IIs in an 1850R

That really depends upon your environment. We have about 20 of these servers in a few racks, and they love their heat. If the processors are the correct Compaq part, I would definately leave the heatsink/fan on them, while they may have a huge dirty fan in front of them, the heat can be taken away much more quickly if they have a heatsink and the fan keeps the heatsink cool!

That said, if you're in an efficiently air conditioned computer room (unlike ours!) and the temperature never creeps over 22C, you should be fine.

Make sure you install the management agents on the server, no matter what OS you have, and set heat thresholds on the server so that if it does get too hot, it will switch itself off and wait for it to cool down rather than melt!!

This feature has saved my arse on many an air con melt-down!

Re: Thinner style Pentium IIs in an 1850R

Thanks Mike.

Unfortunately the server sits in my bedroom, so it's not air conditioned......

After doing some research I have learned that I have put two SECC2 type PIIs in the machine, and although I have removed the small powered fans from them, the small SECC2 type heatsinks are still attached, so hopefully they will be OK. There doesn't appear to be a way of attaching the large Proliant heatsinks to these.

Where do I find the management agents you speak of - are they on the SmartStart CD, or can I download them?

Many thanks

Re: Thinner style Pentium IIs in an 1850R

Well that depends upon what Operating System you're using!

Go to here:

And drill your way down depending upon what server and OS you're running. You may find a few handy Firmware updates on there too. We had a problem whereby the server would forget all its' BIOS information which was only fixed with a firmware update to the system.
