so...
I'm totally stuck on two heatsinks.
after reading copious reviews and reading charts till I went blind, these are the two best for me.
but which one???
SLK-900a with socket clips, or SP-97 with heatpipes and bolt-on, but $16 more...

They're about equal heat-wise, the sp-97 usually wins out in tests, but sometimes it's lost by a decent margin. and it's a pain to install/remove. The SLK900A just clips on, cools almost as well (if not better), and is cheaper.

so is it worth it?
I'm going to OC the heck out of a 2500+ unlocked barton, need it to be cooooool.

Clips can be a liability if you remove the HSF a lot, and the socket breaks.

If you only install it once, it's not so bad to go with the screw-down kind that you have to detach the mobo from its tray just to install. If you install/detach frequently, it's probably worth the investment anyway, just so you don't have to worry about breaking the part of the socket that the clip grabs onto.

very good point.
it's just a pain to take the whole damn thing out, cause I don't have a mobo tray, I have to take it out of the case.
*le sigh*
probably should go with the sp-97

"They" should make a mobo tray that has a nice hole in it right where the proc goes, so you can screw down your cooler without it being a total swearfest.

Why they don't do useful shit like that for case mods, but instead come up with fans that blink at you or windows that let EMI through, I'll never fathom.

I saw some guy the other day who did exactly that. and if I had a mobo tray, that's the first thing I'd do with it.
:-D

those are some ugly ass heatsinks. i read the entire thread in geeks too. the guy talking about the blackbody principles is right though.

a black heatsink will dissipate heat better than any other color heatsink. shiny reflecty things will tend to absorb a good percentage of the heat based on the material, but some fraction of that will also be reflected back down on the processor.

the tough part is finding an black heatsink that matches the ideal blackbody while pulling heat away from the processor. and one needs a smooth surface to equally dissipate heat from a CPU. wikipedia has some good information on what a blackbody is though, if you care to read some more. :)

my recommendation/thought/$.02? whichever ugly ass heatsink you want with a black hole in the middle to just suck all the extra energy away.

yeah, but black paint?
I agree that if you had a dark colored heatsink it'd be ideal, but I'm not slapping black latex paint on a copper heatsink.

see, you're thinking latex paint, which is shiney. it's also likekly to melt under the CPU temps where the CPU and heatsink are in contact. think black matte. what you really need is a product known as "chemglaze z306".

you have to remember that it's just radiation and only some of it is in the visible spectrum. radiation reacts differently to different materials and surfaces. in this case, a shiney surface is likely to reflect back the radiation whereas a darker surface will absorb more of the radiation headed toward it.

this is part of the reason some heatsinks come in colors like blue. not the most efficient of colors, but better by far than colors like yellow.

also, note that many heatsinks you find now are annodized aluminum or another metal. the annodization process changes the color of the metal only on the surface, similar to painting. it does not mean the metal is that color all the way throughout and annodization is much much much thinner than a paintjob would be.

yes, annodization would be nice.
but my argument with that... person... was that this is the best performing heatsink on the market, and there are some with black components out there.
and chemglaze is very different than 'paint'. it's a thermal glaze. ;o)

agreed. it may be the best performing heatsink on the market, but i also see the argument he is trying to make. one would think that anyone designing a heatsink would take blackbody radiation into effect.

ok, its a thermal glaze... it achieves the desired effect though! good luck getting some...
so... I'm totally stuck on two heatsinks. after reading copious… - another LJ. or: how i learned to stop worrying and love this life-thingy
