Is there a S370 CPU that is fanless?

I just got a couple of these:

They have a i815 chipset. They are cooled by one 80mm fan and have external PSUs as you can probably tell from the pics.

Via made some socket 370 C3's - but were any of them able to run fanless?

This case would have good passive thermal potention when horizontal:)

Nearly any Via C3 can be run fanless. Even the fastest ones, at 1.4Ghz produce less than 20watts of heat. With a decent heatsink (most Socket A clipped heatsinks will work) and even low passive airflow, fanless operation should be pretty easy to achieve.

What CPU is in that system. As the side suggests it is a Celly. They can be run with no fan on the sink however all the HP's and Compaqs I have seen in my days that were setuplike this had the CPU sucking air over them or a duct to them. I would suggest a 5V panoflo fan.

i run my celeron tualatin fanless at 14 watts, by undervolting it to 1.1 volts on my SOYO TISU

That must be the 1100 @ 100 that you mentioned in another thread.

I'm curious, what sink are you using, and is there any air flow to it at all?

I'm wondering if it would fit in the case pictured above...

cheers guys :D
I doubt it will take a tuatalin so I will see if I can find a socket C3 locally 8)

yep.

i use an all copper heatsink i got from compusa, but i removed the fan.

your chipset must be the b-stepping, my original motherboard was an aopen 440bx.

unless you want to do some serious modding :)

I have gotten the Tualatin to work on non-Tualatin motherboards by using a "Lin-Lin Socket 370 Tualatin Adapter" (do a Google search on this). They are quite cheap $10-$15 and work surprisingly well. However, they do add some height to the CPU configuration, and it looks like you do not have that much room to spare.

overclockers described an extremely complicated wire-mod.

at the time i thought it was cheaper and better to buy a SOYO TISU than to buy a POWERLEAP adapter.

you get i815ep step B ultra 100 instead of i440bx ultra-33 but lose ECC checking.
