Good morning everyone. This is my first time posting on this forum, which is filled with very knowledgeable users.

I have a question about cooling an old Pentium CPU mounted on a socket A/370.

I need to cool it completely passively.

Do you think this is possible?

I'd like to remove the fan mounted on top of the original heatsink.

I've seen some "thermal pads" for sale online, either pre-cut or to be cut. Can these pads also be applied over the heatsink?

I'm asking because I've seen something similar on eBay, but I'm not entirely sure.

You can see it at this link.

What do you recommend for cooling an older Celeron 400 on a Socket A/370?

I haven't found any fully passive heat sinks for Socket 370/A.

What heat sink models could I adapt? Would specific dimensions be needed?

I've also seen very expensive thermal pastes on the market. Do you think they're worth using? Perhaps thermal paste and a double heat sink paired with thermal pads.

Unfortunately, I can't find a large, fully passive heat sink for Socket 370/A.

Thanks in advance to anyone who can help.
