Thin fin heatsinks and the like....

[alpha]

I know that it's dimensions ssound wimpy, but I've heard great things about thinfin heatsinks. I'm thinking of getting this one

What do y'all think of it?

Get an Alpha or an Orb, those are your best bets for socket cooling, the folded fin heatsinks are way below their scores.

go to www.2cooltek.com (http://www.2cooltek.com)
he has really nice ones for 10$,and they perform just barely under that of an orb or alpha

Be sure to check out his heatsink tests,he has an exellent wah of testing them,and he shows many tests and compare all the major players.

Plus he is a really cool guy.
And shipping is cheap.

I had one of the super-thin, folded foil heat sinks in a HP Pavillaslug 333amd. I first thought the HD was roaring, found after new sink/fan that the fan was the culprit. See, before 2 yr ago, all my pewtin was done in a industrial setting(loud). So I didn't know what appropriate Computer sounds were. The fan was very audible 40' away. Only after getting multiple units did I notice the vast difference between it and other new/old units. Maybe some thermal conducting epoxy to reduce vibration.

I do have to say yes to the fact that 2cool is a cool guy, and he hasent let the $60 grand a month go to his head, but he just does not seem to get the realy cool stuff like orbs, he does not even have syringes of alluminum oxide anymore, decided it was too expensive, if he kept the site updated daily and kept good parts like plycon in stock, I would never go anywhere else!

Ahh well he did have a bunch of ORBs at one point.......then plycon started buying all the surplus...........if you mailed him about getting some syringes in,and told him what was up,he would likely get some more in.

It is my understanding that he is a very busy guy,and he runs the shebang by himself
and has a family.......plus I think he is in the military as well(am pretty sure about that).

He really is a great guy,I know him from another forum,and he always helps people there,and makes exellent suggestions and doesnt try to PimP his business either.
He also always answers emails.

Well, in my opinion, the best shape for a processor cooler is a heatsink with a thick massive bottom. On that bottom need to be a lot of thin long coolingfingers, keeping that fat large thick bottom cool.
The huge heatcapacity of that bottom immediately absorbes the heat from the processor, and transports it fast to the thin fingers to release.

My HS is about 7 X 20 cm, bottom 1 cm thick. Lots of 6cm long fingers on it. Proc. temp is 27 C, when room temp is 21. Yeah, I needed to cut and drill some holes in the bottom to fit over some capacitors near the socket. And the processor is not straight in the middle of the HS. No problem.

So, find a piece of this, and keep it as big as possible. Attach some fans with glue on top and there you go!

Costs me about $10. Took the fan for free from a dead PS.

So, I believe in HUGE.

The orb is impracticle for my system space wise. Besides, I don't want a few punds of heatsink tearing off my socket (yeah, I know it probably wouldn't happen but hey! http://www.sysopt.com/forum/wink.gif)

I think I'll get the folded fin heatsink, so I won't have to modify my socket lever.

Thanks for the input people. Feel free to drop in anymore thoughts! http://www.sysopt.com/forum/smile.gif http://www.sysopt.com/forum/smile.gif

A heatsink with a thick base is good, but too thick is bad. A large mass can hold a lot of heat without disipating any of it. If there is a lot of mass between the heat source and cooling fins, the temps where that mass connects to the CPU can get quite hot, even though the fins could get rid of that heat. You need enough mass to contain the required amount of thermal energy, yet still transmit it fast enough to the fins.

As an added FYI, I was getting 9C rise over room temps on my Celeron 333@500 with a retail PPGA heatsink MUCH smaller than you describe. All I had to do was lap the sink and CPU. Not to dismiss your results, which are very good, but just to say that big is not always the answer.

I know what you mean 800XL, but the problem is right here: How to get rid of that last bit of heat! I guess I am almost near the max what you can get with just HS and fan. I mean, if I cut my HS in half (and why should I ??), the processortemp will maybe raise only 1 degree celcius or so. And, yes I'm gonna lap my processor too!

And about how I fixed this aluminium Goliath to my processor:

I have a tower model case so the mb stands right up. The HS is attached with clamb and spring to the socket 7 processor, and on both ends I glued a piece of rubber between the mainboard and the heatsink. (It is a removeable glue, like the stuff on tape)

And it fun to show! When I open the case to let someone see the inside....

btw: a prefab heatsink is made in optimal dimension/capacity ratio for its job, I guess... No manufacturer want to spoil expensive material and prodictivity...
