Sorry mingon,
You're wrong.
Frosty Tech Heatsink reviews
Regardless of heatsink, the smaller contact surface tests result in
higher temps than the large contact area's. NO, the frostytech die sizes aren't exact analogs, and the temperature differences are probably a bit exagerrated than will be between palomino and Tbred, but the fact remains: Small die size hinders heatsink performance.
I mean, even look at the respectable Swiftech MCX370 and it still shows a significant difference between the two die sizes.
And to further show some data, let's apply 80W of heat to the small contact surface, and 100W to teh large contact surface.
arkua 628: Large contact surface =
57.5C. Small contact surface =
50.88 C. So this heatsink has good large/small die size performance.
swiftech mcxc370: Large contact surface =
53.5C. Small contact surface =
52.56. Similiar performance between teh two die sizes, but the small die size is
20W cooler.
Taisol CGK760 (heatsink inlcuded in tbred reviews): Large contact surface =
61.2C. Small contact surface =
62C. Again, comparable temps but the small die size is 20W cooler.
Now, let's examine the difference between an XP2100+ palomino and an XP2200+ Tbred. How many watts diference?
~4C.
And do I really need to go back and quote several (in fact, most) Tbred
reviews from monday that said the same thing i'm saying? And for you to say that system integrator's use quality materials is
extremely laughable. I've seen many computers built with subpar, junk OEM heatsinks for the purpose of saving $3 over a coolermaster.
When you shrink the die size of a CPU, and shrink the corresponding contact surface, you concentrate the heat transfer of the primary heat pathway. Depending on the heatsink, some will choke up when trying to spread out 65W of heat over an 80sq mm contact surface. That same heatsink might not have an issue doing the same wattage with a 128 sq mm concact surface. WE're not talking
insignificant die size change. its a drastic drop in die size.

Again, higher end heatsinks should have no issue with tbred 2200+'s running hotter than XP2100 palomino's. I'd say everything from Alpha pal8045s, swiftech models, thermalright models, higher end copper models will be fine. But i've seen hundreds of cheap heatsinks with very poor base qualities, noticeable machining marks, etc. On these heatsinks, including thermaltake units, the contact surface could potentially be further reduced due to
poor base quality. With the heavy machining, what if hte effective contact surface is now 70 or 60 sq mm. Even with a good grease, this would be a huge heat issue. You're not alking aobut 70W off of 70sq mm. Again, it will make a difference on those heatsinks.
