Hi DCypher:
___I hope this will answer some of your questions …
1) A funnel is exactly what you described. Its simply a 60x60 to 80x80 plastic adapter. Plycon has them as well as a few others.
2) Most all the 60x60mm fans for T-Bird/XP + HS’s come with the ridiculously noisy fans if they cool worth a darn IMO. This is where the funnel comes in. You can attach an inaudible 80x80x25 mm case fan to one of these great T-Bird designed HS’s using the adapter and cool a PIII/Celeron std. as well as the PIII/Celeron III-Tualatin’s much better than a Retail F/HS as well as any concoction of 60x60 mm fans on just about any high performance HS for the CPU’s listed above. As an example, my 1.0A barely makes it to 1.342 GHz using a Silencer/Funnel/DY1206BH-625 Dynatron solution. With the retail, it won’t even post at that OC … Temps are only 5 – 15 degrees above ambient using OC’ed Coppermine’s or Tualatin’s at 100% load with this solution yet the setup is only ~ 20 dB inside the case and
3) As Voop mentioned, I don’t like the Zalman’s either. The thermal performance of all the Zalman CNPS’s are poor once again but they can be very quiet.
___As far as picturing this solution, I left the viewable linked jpg’s in the “Best in Class†post.
___StvB, it is the 60 finned -1206 micro-finned/skived units from Dynatron that are not made for the low RPM fan solutions. The -625 is a special case in that the 36 fins are not nearly as tightly packed for good air flow through them with out all the DP losses as their monster packed 60 fin brethren. The -625’s are also unique in the way the fins are soldered into place with the 3-prong clip already installed. I use both the SVC Goldengate and the Dynatron -625’s with great results for the PIII/Celeron solutions.
___Finally, the copper based Dynatron’s w/ the high speed 60x60 mm fans have shown good results on top of high frequency T-Bird’s/XP +’s but they don’t work worth a damn using low RPM case fans and funnels. This is where the Alpha’s PAL 8045’s and 8942’s for the P4’s come in as far as a quiet solution with good thermal performance. I rant about the Zalman’s and Molex’s simply because for the price you pay, these things perform very poorly whereas for a few dollars more or less, you can have solutions that are either as quiet or quieter and also provide huge gains in thermal performance in comparison.
___Good Luck
