Doesn't look so bad to me. What do you think?


Peace,


:cool:

Better than that giant circular thing they displayed before.. this will have no trouble fitting in smaller cases.. looks like a high quality HSF for a stock one! I wonder what speed the fan will be? i guess intel were aiming at keeping the thing silent and upping the quality and heat dissipation ability of the HS instead of relying of a higher cfm fan.

I'm just hoping that this isn't going to be a good indicator of Intel's retail cooling solutions for Prescott. 6000RPM @ 48dB is a bit too high of an upper limit for me.

trying not to break nda

intel is looking into "other" methods right now.

70mm 6000rpm fan ouch, thats the same as my Volcano+ at max speed. Although that is at 55C, however if it's anything like i have seen it will hit that everytime you run a game.

Faster fan too? oh, then thats no good at all.. they should go for an 80mm fan.

I agree, it should be a 80mm or 90mm fan if it needs that much cfm. At least those don't have to run at full speed to deliver the same or more cfm like a 70mm @ 6k rpm...lol.

New 2.4Ghz Northwood C's with the SL6Z3 are hitting 3.6Ghz with either stock or slightly increased voltage and stock HSF. I'm not worried about Intel at the moment. :D

Peace,

<3 thanks, J :)

Theres not a great diffrence from a 8cm & 7cm fan.

[Eck]

80x80mm = 6400mm^2
70x70mm = 4900mm^2

That's a differnece of 1500mm^2. It makes more of a difference than you'd think....

I'm guessing "other methods" includes either one of those wack turbine fans on high end HS's or peltier cooling.

Edit: To better show fan size differences, hers some spec from Newegg:

80mm fan:

ThermoFlow TF8025 Temperature Control Sensor Adjusts Fan Speed Automatically. 80x80x25mm / 3.15x3.15x0.98" Fan, 2-Ballbearing, DC 12V, 1.8 ~ 2.8 W, 1950 ~ 3400 RPM, 23.8 ~41.6 CFM, 3-pin with 3/4-pin adaptor. MODEL: TF8025

92mm fan:

ThermoFlow TF9225. Temperature Control Sensor Adjusts Fan Speed Automatically. 92x92x25mm / 3.62x3.62x0.98" Fan, 2-Ballbearing, DC 12V, 2.0 ~ 3.12 W, 1850 ~ 3100 RPM, 34.8 ~ 58.5 CFM, 3-pin with 3/4-pin adaptor. MODEL: TF9225

As you can see, that 12mm or about 15%, makes the 92mm fan push about 50% more air, even though it's running 100 rpm slower. That means an increase on Intels fan to 80mm would probably push 40% more air. Going even further, that means a 92mm would push the same air as Intels 70mm running at half the speed(3000rpm if you're a moron.) ;) And a helluva lot more silent.

your figures are wrong...

fans are circular, so...

80mm w/o deadspot = 5024mm^2
70mm w/o deadspot = 3846.5mm^2

but your point still stands

There is also the fact that P4's chips are alot smaller.. i know the die is what matters most but with the heat spreader the overall size matters too... the 'dead spot' on an 80mm fan will leave alot more of the CPU out of the full flow than what an 80mm fan on a K-7 or K-8 AMD processor. I guess this must be intels reason for not moving to 80mm.. i'm pretty sure AMD have with K-8.

92mm is out of the question even for AMD processors.. they are extremely large and not suitable for every situation. Also.. remember intel are meant to be keeping compatibility with current mobo's, this means the HSF has to fit in the current mounting bracket. I'm not sure if it could fit an 80mm fan.. i know the current fan is much smaller than the bracket, but 80mm may be too large... i guess the fan could be larger than the heatsink and have one of those converter type things.. you know the xxmm -> xxmm conversion bracket things.
