Greetings from Croatia.
People from Croatian Forum PC expert advised me to ask you. Here's a question. Can Scythe Ninja 2, fanless, cool quality 754 Athlon 64 3200+ and AM2 Athlon 64 X2 3600+?
Thank you.

It depends of load/use and case cooling, however the answer tends to be positive.

The socket 754 cpu has a 89W TDP and the AM2 cpu is 65W. I'd say maybe on effective passive cooling. As mentioned above, it depends on the load case and whether or not there is any other airflow in the case, ambient temps, etc.

Thank you.

Dobrodošli, greetings from Poland :) I used to have a slightly overvolted Venice 3000+ @ 2,2GHz with fanless Ninja (the first one), all packed in Antec SLK-3000B with just one exhaust fan on the rear of the case and it worked fine for almost two years. The CPU would mostly play games and render some simple graphics, no problems at all. Can't remember exact temps, but even at high loads the cooler was warm to the touch, never hot (outside temps reaching mid 30's in summer).

Now since the CPUs you mention have higher TDP than mine had, I expect them to tun a bit warmer, but the Ninja should be more than enough to cool them in fanless mode. Take a look at this site for TDP's of older Athlons for reference.

First thanx for comments. This computer is not for gaming. The computer is in the bedroom connected to my audio, monitor, TV and local network. The case is open, on the processor is Zalman 90mm but I could get the Ninja 2 cooler for small money. I'll get a passive power supply for this computer (PC without fan). Summer temperatures in my area (Vinkovci, Croatia) are around 40°C. Will that be sufficient cooler in the summer?

Are you either just looking for being extra confident, or actually teasing? http://www.yr.no/place/Croatia/Vukovar- ... stics.html

I've looked at some statistics about the temperature in my area but it does not agree with the actual temperatures in the last 10 years. I have a thermometer and I know what is the temperature in my area. Believe me that the temperature may be 40°C.

I am not in the conditions of being able to trust your words "sic et simpliciter": at any rate, do your math.

As a somehow educated guess, you cannot expect a rise over ambient less than 35-40°C at load (and you can't expect far better figures at idle/low load with such old CPUs), maybe more (in a reasonably worst case, you may think that rise over ambient may raise up to around 60°C); providing that, you may guess then how far you can go.
Obviously, without a first hand experiment, you can't really know.

Whatever. I ordered. Cooler comes tomorrow or the next day. When I install the cooler I'll tell you.

There was a problem with the Scythe Ninja 2 cooler. Seller changed his mind. I was looking for something and found:
1. Thermalright Ultra-120A 4 Heatpipe
2. Thermalright Ultra-120 Extreme 6 Heatpipe
Both coolers are fanless. Again the same question. Can these coolers cool 754 Athlon 64 3200+ and AM2 Athlon 64 X2 3600+? If anyone has experience with these coolers I could use some help. Thank you.

Why bother with fanless? You will probably need some kind of ventilation since it's difficult to cool a CPU like that completely fanless. Just strap a slow silent fan to the heatsink, done.

Semi-fanless is possible if the general airflow in the case permits it, but then you will probably want a cooler with lots of space between the fins. The Ninjas are good for this purpose. The Thermalright coolers are very good, but fin spacing is tighter, meaning it's probably safer with a fan.

Also, while it's great to reuse old hardware and give the stuff a new purpose, sometimes it's not worth the hassle. A modern system for HTPC use can be small and silent or very quiet, and draw quite a lot less power. But it will cost a bit more. Image

Thanks for the suggestion for the Thermalright Ultra-120 Extreme. I'll buy that. I'll try to set up without the fan. If the heatsink is not enough for Athlon I'll try to passively cool my P3 in home recording studio at my cottage with this cooler.
