What heatsink/fan combo do you recommend for high end P4's? Prescott's in paticular(Socket 478). Thanks for any opinions.

I've got the Zalman CMPS7000 Al/Cu for my 2.8C

good cooling and nice and quiet
 
I'm running the Gigabyte 3d Cooler Pro

This thing kept my 3.0 (northwood) under 40c at full load with the cpu overclocked to 3.9+ghz.

With the Prescott 3.0E, running at stock speeds, idle is sitting at 49c, haven't checked load temps yet, but going to re-apply heat sink compound and reseat the cooler as it seems too hot to me.

Prescott cores are known to run a lot hotter than northwoods as well as perform slower than northwoods up to 3.4 GHz

try Thermalright's SP-94 + 92mm fan
 
I have the all copper Zalman 7000. not very loud, and damn easy install. alot has been said about this unit's weight but it has not been an issue for me.
 
2.4C @ 3.0 with my Swiftech MCX478-V P4 and 92mm Panaflo. It barely fits in my cube, but it's in there :D

had that same combo awhile ago. the CNPS7000's are good coolers and fairly quiet at even 12v fan speeds. i'd recomend it.
 
Thermalright SP-94 + Panaflo 92mm

Excellent cooling and almost complete silence

SP-94 with any quiet fan would be great.

My question is, would a SP-94 with a very low (>25cfm) fan cool better than a Zalman? I'm running a Zalman 7000alcu now, and love it.
 
Try beating SwiftTech's MCX4000 (about to be upgraded to a MCX478-V) combined with the power of Vantec's 80mm Tornado (about to be a 90mm when I upgrade my mobo)....

But you'll need a fan controller...it makes a BIG difference...
 
My new Prescott 3.0 sits underneath a Zalman CNPS-7000Cu without the little rheo they come with (WFO all the time) and an appropriately thin layer of Artic Ceramique.

With a 3.2G OC, I'm currently running mid 40's on idle, mid 50's under load. Even without the little Zalman rheo, it's quiet, too - no "Lear jet on a short runway" issues...... :D

Party On - B.B.S.
 
I'm using generic compound and the stock heatsink/fan that came with my 3.0 Ghz Northwood. I run 45 idle and around 51 at load.

Before I lapped the heatsink I was getting 50 at idle and 56 at load . Also, I have the Abit IC7-G with the bad temperature sensor, so I figure I'm running at least 5 degrees cooler than my bios is reporting.
 
i use the zalman as well, excellent buy! i run the speeds shown below under full load with temps that go no higher then 41C (mobo does not exceed 39C)
 
Zalman 7000Al-Cu on my Mobile P4, kept well under 50C up to 4Ghz
I, personally, think it's too loud, but when turned down with the included fan mate it's reasonably quiet. Another added bonus is that it can be mounted on all the platforms I own (462, 939, 478) for the exception of my elderly williamette board.
 
So as it turns out my MSI board just didn't like that prescott cpu, i.e. the mobo died on me.

I put it into the other machine I've got here, which uses the ASUS p4p800 deluxe motherboard and temps dropped down to 40 idle, 47 under load (transcoding of movies, cpu pegged at 100% for over an hour).

So it looks like the 3d Cooler Pro was doing it's job and is back on my recommended cooler list :D

Update:
Overclocked to 3.6ghz (via the 20% oc in the asus bios) idle temps are at 43 and load got up to 56.
 
I'd recommend the SP-94 as well... I have the SLK-948 and it does an awesome job on my Northwood ( 33°C idle.... 41°C load at 1.53V), but I wouldn't recommend it for a Prescott.

I'd go with something that has heatpipes.... the SP-94 and the Hyper6 would be my first few choices, the Hyper6 gets lower temps than the SP-94 but you can probably get the SP-94 for less if you're looking to save a little money ( plus the SP-94's about a half pound lighter :D ).

For a fan, I'd get the Delta HHE from Sidewindercomputers... it puts out 74 cfm at 43 dB. It puts out twice the pressure of most 92mm fans ( it's half the pressure of the 92mm Tornado, but it's also 15dB quieter). Pressure is one of the most important factors in a HS fan b/c it's what pushes the air all the way to the base of the HS to cool the hottest areas. Most fans have back pressure or only cool the top part of the fins b/c they don't produce enough air pressure.

The HHE is out of stock right now, but I emailed them a while back and it shouldn't be too long before it's back in stock.
