SI-97 fanless on 600mhz cpu?

Depending on the airflow/temperature/etc in the case as well as longterm load, it may suffice.

IE if your case temperature is 50C and you have 100CFM airflow without the current fan around the cpu socket, that probably will still cause problems for your chip.

Contrary to that, if your case temperature is only 20C yet you have < 5CFM air flowing without the current fan around your CPU socket, that probably will not be sufficient either.

Since there are so many variables that is why oem(and I mean /real/ oem of the processor, like in retail packaging) heatsinks are usually mated to a decent fan to ensure a more reliable customer experience.

Having said that, in open air(no case) heatsink up at 20C, it should be sufficient. There is an earlier zalman (flower) heatsink designed passive cooling that work quite well as well as some of the newer tower ones that you may want to look at first.
 
Checkout the CNPS 6000. The fin style is more appropriate for passive cooling.

Without going fanless you may want to try the cooler si97 with a really quiet fan, which in my opinion would be your best bet. the si97 mated with a Nexus 80mm or 92mm would be virtually silent. Much better than any SilenX or north-american Panaflo. The downside is that fan would cost you another ~ $12 or so on a good shopping day.

You could always try it fanless, then buy a fan later so long as you watch the temperatures carefully, and floor it for a day straight atleast before passing it back to your Dad.
 
ok I appreciate the tips. I was hoping that the low clock on the Duron would let me go fanless easily with a 90mm thermalright. I may consider paying more for one designed to go fanless just for the peace of mind. Thanks.

Personally, I wouldn't try going fanless with the SI-97! No way!

I always look at the fin density on coolers. If you start doing the same, you'll notice that fanless heatsinks have low fin density.

The SI-97 looks like the fin density is pretty high, which means it was designed to be used with a fan -- and one that pushes a lot of air.

For a basis of comparison, check out the Scythe Heatlane Zen NCU-1000 fanless CPU cooler. I know this is an extreme example, but you'll see what I'm talking about... 😉
 
That's great info thanks. If I recall, the XP2000 was a Palomino core and those ran pretty toasty. I'm surprised you were able to run a fanless hs with that cpu, good case ventilation or not.
