Cooling Socket 370/Slot 1

Folks,

I know it's old technology... but it's cheap technology.

I'm looking at building a system based on a Pentium 3/Celeron in Socket 370 format. However performance heatsinks for these seem very hard to come by.

Is it possible to fit modern heatsinks such as the Ninja to 370 boards in any way? How do the chip sizes compare?

Would slot 1 be any easier?

Ideally I'd look to go fanless...

Cheers

Steve

Hi Steve,

I have a socket 370 Pentium 3 machine, the best heatsink I was able to find was the scythe katana. Works really well.

Sadly my board doesnt have temp sensing so not sure on exact temps but if you have a search around you'll see it works pretty well.

Really, really easy to install too.

Hope this helps.

EDIT: Just like to add i have it ducted to the back exhaust vent and its the only fan running in the machine (with a fanmate too).

I think it's definitely easier to passively cool a Socket 370 CPU than one using Slot 1. I remember some PC builders using Slot 1 Pentium IIs with large passive coolers, but most of the coolers used noisy little fans. Any decent Slot 1 coolers are pretty hard to find these days. Socket 370 is compatible with Socket A coolers, they offer a lot more choice and easier availability.

Generally P3 CPUs have quite low power consumption and don't require a lot of cooling. I've run an 800Mhz P3 passive with only a cheap aluminium cooler (IIRC a stock cooler that came with a Socket A Athlon), the temperature was fine with only a low speed PSU fan moving air over it.

It seems like overkill to use a more advanced (and more expensive) heatsink like a Scythe Katana or Thermalright Si97 on such an old CPU. You'd probably be spending more on the heat sink than the value of the CPU and motherboard combined.

I'm using a hacked up custom heatsink on my socket 370 celeron 800 cooled by a single 120mm Nexus intake fan in my p180. Temps hover in the mid 40's but tend to rise up to 60C under load.

With summer coming around the corner, I decided to upgrade to a SI-97 which should be here in a couple days. I also have a Katana cooling my Socket A tbred processor so I do a little experimenting to see which performs better.

As suggested above, the SI-97 and Katana are 2 very good choices for Socket 370 processors.

Thanks for the tips.. Have just aquired a QDI BrillianX 9 Motherboard with PIII P3 700 MHz CPU 370. The QDI seems to support limited undervolting so that may help...

Any suggestions on a cheap Socket A (370 compatible) heatsink?

Cheers

Steve

I'm using a Nexus AXP-3200 on my 1.2GHz Celeron/ASUS TUV4X:

I purchased a plastic duct adapter, and have a Nexus 120 mm fan blowing air down through the aluminum fins. (The original fan isn't that great and is fairly loud.)

There are pictures of the AXP-3200 on EndPCNoise:

For slot 1 you are stuck with the HS,could bungee a bigger fan to it,or do a bracket-which makes a 120 low rpm workable. The minimal Sempron/matx package is so cheap-I would not spend much to do a slot 1,but Coolermaster and Evercool do have low rpm 120's under $10
