Anything should be fine. Arctic Silver is the best but a server on stock clock isn't going to be too hot - especially in tower form.

Interesting that just a few minutes before the OP came live I thought the same question... "What if we were to put a second CPU in our server, what kind of paste would we need?"

If you purchase a HP Spares second CPU and heatsink it will come with the paste already on the bottom of the heatsink.  HP use a "thermal pad" type conductor.

As for other types of heatsink paste, since you are putting it in a server (which i assume is a production box) i would personally use the best type i could find, not the cheapest stuff!

Question, how come you need to replace the heatsink paste?

Is the question for me or the OP? I don't need to replace anything. Just thinking on adding a second CPU, but didn't know it was bundled with thermal pad...

jaymz: thermal shutdown event on a ml350g4, problem is it doesn't seem hot, nor are the fans working hard, it may be a faulty sensor, but it's shutting down the server. If this doesn't work, based on it's age I will recommend replacement.

It would be cool if there was a way to view a thread as a thread, so you could reply to specific comments to save confusion.

Sorry the question was for the OP.

Generally, unless the heatsink has been removed before from the server the factory thermal paste should be sufficient on those boxes (I have the exact model)

TBH i think it is a sensor rather than heat transfer issues, but try the thermal paste (quick fix). You could also run the Insite Diagnostics CD against the server and find more information about the thermal shutdown issue.

@freitasm: Yup, if you buy a factory replacement/spares/addon from HP you get the CPU and heatsink with a fan. On the base of them is a grey thermal paste pad. This has been the case with ALL the HP servers I have worked on (ML350 G2 through to ML350G7 and DL160G3 through DL380 G7)

Thermal shutdown definitely caused by the cpu?

These are interesting:

Probly just improved paste but might an updated heatsink if you order genuine.

The existing stuff was literally crumbling away, temp seems to have dropped on average around 9 degrees, but we won't know for a few days.

That second advisory looks like us, nice spotting and thanks for the assist.

I am still going to push for the client to replace this server, it's getting pretty long in the tooth now.

i got a replacement CPU sent out for a bl460c blade a few weeks back.  it came with a tube of paste - they sent the CPU only, not the heatsink.   You only get the thermal pad if you get a CPU+heatsink at the same time
