Thermalright SK-7 $14.99

You should always have a fan on a heatsink blow into the hsf...all coolers that come with fans pre-installed are like this.

You have never used an Alpha Heat sink or other shrouded heat sink like the Kaney Hedgehog that instruct you to have the fan airflow away from the heat sink.

I admit haven't looked enough into the air flow recently, but I agree for today's fin configurations you should blow into the heatsink. I have experience with 'older' shrouded HS's as mentioned above, and haven't used a stock HS/fan combo in forever. Only in the last year or so I've moved to quieter solutions with bigger fans, now exclusively with the SLK's.

I can still hear those 60x38mm sunons and deltas ringing in my ears

Crashed connection, apologize if this post duplicates..........

I wanted to let everyone know that it's back in stock.

If the shipping takes a while call to complain. I did and they sent me fedexed me the same stuff ordered overnight - sweet. =))

Well, I have to retract all the bad stuff I said. I emailed the owner and informed him that I only recieved 1 when I ordered and was charged for 2. He emailed me back saying that the second one was backordered and would ship as soon as it arrived.

The second one arrived yesterday and it had a third SK-7 in the box as a bonus. I'm happy. Got 3 for the price of 2.

...then edit your original post where you sh!t all over them prematurely.

 

[KokomoGST]

Well, they were backordered last time I tried to buy... finally I can get a less noisy HSF.

I was very happy with my purchase, for what it's worth. Thanks again for the OP.

Yes, I have mine blowing into the heatsink, and I think most people have it this way.

There is an important manufacturing difference between the AX-7 and most other heat sinks: the direction of the extrusion of the aluminum. On the vast majority of heat sinks the direction of extrusion runs across the face of the IC. This results in aerodynamic edges of the fins meeting the oncoming air coming down towards the processor. This gives you the lowest noise for a given volume of airflow. The square edges of the fins are at the areas where the air leaves the HS.
The AX-7 direction of extrusion is perpendicular to the plane of the face of the processor. The aerodynamic edges of the fins are designed to meet the oncoming air coming from around the perimeter of the HS and moving in towards the center. This is why this heat sink is more efficient with a fan blowing away, in terms of heat dissipated for a given noise level, at least.

Will these be compatible with with amd's future chip, like the 64-bit amd chip?

 

[c627627]

Word is no. Socket A CPUs only.

Don't be too sure. SK-7 has nice base that is used to put adapter for 478 socket and it seems that is performing excellent, for less than $5. I imagine something similar can be done for other sockets as well.

That is not true. You apparently have not seen Zalmans.

Will this work with Duron 750 MHz? Do I need to get a Panaflo fan too?

My Duron 750 MHz (oc'ed to 850 MHz) with OEM fan runs way too hot with high CPU usage (> 56 C)!

Is this combo the best bang for the buck?

That is an overkill for Duron.

 

[Slickone]

This (SK-7) is only $.90 cheaper with shipping than SVC's normal price with shipping. And if ordering other items with it, SVC may come out cheaper.

Well, running at 56 C right now is killing the Duron... :frown: If I upgrade my BIOS I think it will be worst. I have an Abit KT7A-RAID (1.1).

Also, I assume I can still use the same SK-7 and fan when I upgrade to an Athlon T-bird 1.1 GHz. Right? I think that's the fastest processor the MB can take.

Should I get the AX-7 instead?

Seems like when I first got my AX-7(it's been like a year ago so I'm a little foggy) I tried reversing the fan(blowing away from the heatsink) and got either no noticeable change in temp or maybe even an increase. Can't comment on the noise issue though.
