Scythe ninja passively cool a 3700+?

Hi there, I was just wondering if a ninja can passively cool a San Diego 3700+ if it is not overclocked? I will be using it in a P150 and adding the 2 front 92mm fans, hopefully on low speed all the time, just to get better airflow through my case.

Other components are an Asus A8N-E mobo, 2 x 1 gig OCZ plat ram, Western Digital 250 GB with 16mb buffer hard drive, HIS X1800XT graphics card(replacing stock with zalman VF900 for quieter running).

Thanks for all your help, it is very appreciated

PS Before I place order for case is it worth paying the extra to get a P180 and a NeoHE separately?

Hello,

The short answer is: probably. My X2 4200+ is "passively" cooled some of the time. If it goes above 52C, then the rear 120mm exhaust fan comes on, and it never goes above 54C with both cores running Folding@Home. The case is an Evercase 4252 and the PS is an S12 430, and there is a single 92mm front intake at 5v, and I've undervolted it by about 0.075v. It is running at the stock 2.2gHz.

Have you checked on the compatibility of the Neo HE and the Asus? If you have just the one drive, then the P150 is probably the better case.

Yes, and quite well too.

I have an X2 4200 passively cooled w/the ninja. I have 2 nexxus 120's in my slk3000b at standard voltage running all the time. I have no problems with temps at all. Highest I have ever seen the cpu is 57 celcius.

I would doubt you can run it completely passively, but you can run say a nexus fan at very low speeds so that is almost inaudible and cools sufficiently. I found this out playing with my Opteron 165 undervolted to .99V and still found out that dual priming still caused temps to go up considerably (+48C), until i manually turned on my fans to its lowest possible setting:

btw> I would caution not going over +55C too much. You are close reaching the tcasemax of ~60C. I try to stay under 50C at all times.

I second that

I have the Ninja with an Antec TriCool fan on medium setting at 5V on my overclocked and undervolted Opteron 144 (2.9GHz, 1.3V), and it stays at 46C while priming. Taking the TriCool fan out makes no audible difference, but the CPU temps go above 50C.

This is with two exhaust fans (Papst 4412F/2GLL) in my P180 running at about 750rpm after CPU temps reach 45C. Below that they run so slow that the rpm sensors don't get a proper reading... CPU idles at about 36C.
