i love this channel :))
i have an Alpha 6035 hs and put an 80 mm Sunon (high out put 40 cfm fan with adapter)...i opted to go this route cause its much quieter than going with the 7k delta fan. Its on top of an amd 1.2 gig chip.
My question is ...is this a good way to cool my bird. i do want to overclock the cpu, and am a little nervous not to fry another one :)

i have overclocked my first 1.2 gig cpu to 1391 mhz.(13x 107)....but it didnt last long...:(...i think my case ventilation is pretty good...and hardware monitor had temps @ 38oc....underload running 3dmark 2000....then everything went black bout 15 min later...(ran it a couple of times)

any advice would be appreciated....

ps..i dont want to buy another hs/fan as wife thinks im nuts already....
with that in mind what you guys think i should be able to clock to

sorry for the long winded explanation!!!

my sys:
amd 1.2 gig (200 fsb)
256 generic pc133 ram
32 meg msi gforce 2 mx
maxtor 20 gig 7200 spin
maxtor 30 gig 7200 spin
old hp burner
lg 8x dvd
enernax 350 watt ps
120 mm intake fan (front bottom)
80 mm exhaust fan (rear top)

You've got a pretty jammin' heatsink/fan combo there. I think at best the thermoengine would buy you a degree or two celsius. If anything at all. Not worth it.

The thing that you can try to do to get a better overclock is bump up the voltage a little. Like anything keep in mind the extra heat that comes along with higher voltages.

Don't feel too bad if you have to drop down a few FSB increments though. The mid 1300's is not a bad o/c on some 1.2 GHz Tbirds.

As I understand it, to equal the cooling ability of the Delta 38, a much more powerful 80mm fan must be used. This is because even though a larger fan pushes a larger volume of air through the HS, it can't equal the pressure that the Delta 38 musters.

I've read that a 68 cfm 80mm fan must be used to equal the cooling ability of the Delta 38. Who makes such a fan? Why Delta, of course! And it's loud, too. The beauty is that it is a lot less annoying than the 60mm Delta.

You can buy the 80mm Delta "68," a Sanyo Denki 53 cfm 80mm or an 80mm Sunon 50 cfm from kdcomputers.com.

thx kloster64a for the reply.....sorry for the delay in responding (was away for a couple of days)....i had a concern bout the pressure issue after i did a little test of my own. I just put the fan up to the hs while i was holding it in my hand. I noticed the rpms dropped quite a bit....hence the pressure concern.....is there some kind of formula i can use to figure out how much torque the fan needs to be effective??
