A64 mobile or not

Well I'm helping build a media PC for friend. No DVD watching but music and photo and web surfing. He wants noise to be kept to an absolute minimum so I suggested a mobile A64 (understanding that they run on S754 mobos) to keep heat/fan noise low.
Is this a resonable option or should he just go with a Winnie and hope the CnQ does the rest of the job for him?
no mobo purchases yet, but it is imminent and looking for a little guidance here.
 
Winnie CPU with an XP-90 heatsink and 92mm low RPM silent fan runs super cool and almost completely silent even without CnQ feature turned on. At stock speeds my system idles at 27C with the XP-90 and Zalman silent 92mm fan at the lowest setting. Any quality heatsink with a large, low RPM fan should be fine for a Winnie.

Even at the listed OC speeds, my Winnie is still sufficiently cooled (idle high 30s, load mid to high 40s) at the lowest fan speed setting using the XP-90 and 92mm Zalman. The key is using a 92mm or 120mm fan as you get much higher flow with lower rpm's compared to 70mm fans. If I remember right, my fan only spins at 1600rpm, so I don't think it gets much quieter than that unless you go passive.
 
The low voltage mobiles are the only way you will be guaranteed low voltage/heat...

BUT, for instace my S754 2800+ runs stock (1.8ghz) at .950v... It was idle 31oC and Prime95 load of 33oC, with the stock heatsink and thermal material.

I almost unplugged the CPU fan to see what effect it would have on temperatures, but instead I went straight to overclocking...

I'll have to disagree with that considering the huge body of evidence from basically every 90nm 939 A64 owner who has posted on stock temperatures on this forum that I've seen. The noise level on either the mobile or Winnie depends on the fan you choose, and neither chips have ever had heating problems at stock speeds when installed properly. Unless you go for passive cooling, either chip will run COOL on a 92mm fan at ~1500rpm and almost completely silent.

Will the mobile run cooler with the same fan? Most like yes, but is there a difference in running at 27C idle on a Winnie versus maybe 25C on a mobile ? I would say no.

For just web surfing and looking at plain photos I would personally go with a Winnie and an ATI Xpress 939 mobo with integrated X300 video (the MSI board has all passive cooling so no noise and is $92 shipped with the most powerful onboard video available) and pair it with an XP-90 heatsink and large low RPM fan. Then you have something that is dirt cheap, yet upgradable with future CPU's (even future dual core athlons will work on current 939 chipsets), future PCI-E video cards, and of course be silent. Just my 2 cents.

I think you mistook my post. I agree with everything you said. I was just stating that the true mobile's are the only chips guaranteed to run at low voltages (which inherently mean lower thermal output).
 
Cool. (Pun intended) He's decided to go with a Winnie cuz they have pretty low thermal output and the hassle factor is quite low.
Deciding on which mobo - he wants 2 Lan ports on-board so looking at options from MSI - the neo4 platinum.

Thx for the input guys!
