what are some of the best heatsinks for a socket 775 pentium 4?

Scythe Ninja.

But you need a gigantic case.

Arctic Cooling Freezer 7.

P4 775 640 @3.2Mhz.

Current ambient temp 17C.

No load cpu temp 26C - Load temp 36 - 37C @3.6Mhz using arctic cooling tim.

Zalman7700 in my sig

53C full load prime 95 10 hours @ 3840 ghz
55C @ 4004 ghz Prime95
at 85 deg F amient temps

I purchased a Masscool heat sink and fan. It was $19.00 and it keeps my 3.2 Ghz P4 between 36C and 50C. Room temp verys between 65 and 80 F.

EDIT 36 - 40C Idle
45 - 55C Playing Grand Theft Auto 3

The Zalman CNSP9500 works well, but like the Scythe Ninja, you need a big case for this one.

7700 zalman

Scythe Ninja. I'm planning on using it to passively cool a Conroe that is not overclocked.

Another vote for the Zalman 7700CU. $50 at Fry's, probably cheaper online (I'm the instant gratification type tho lol)

I use the Cooler Master Hyper L3 with excellent results.

Can you post these excellent results? Otherwise your thread is useless...

He asked for a suggestion, I gave one...just like everyone else. It was a post, not a thread. Your post is useless.

i would recommend the Thermalright Ultra 90....

I'm asking because some people think that 50 deg Celsius is ok idle temp, so I like to see; idle:***, load:***. No hard feelings.

I have used the Thermaltake Big Typhoon with my 840 @ 3.840Ghz on 1.40 volts with 45c idle and 50c full load at 32c room temp. Thing is it's pretty huge and may not fit in slimmer or smaller cases. Im using Thermaltake Kandalf full tower case by the way.

Look at the Thermaltake Sonic Tower 112

I second on getting a Big Typhoon. It is the best air cooling solution I've ever seen.

Ambient of 22C
Idle @ 25-28 (28 when PC has been running for a day or so)
Load @ 42-46 (Fluctuates back and forth a bit when)

with an Arctic Cooling Freezer 7 Pro and Arctic Silver 5. Really impressed with the cooler for a 21.99 on newegg pricepoint.

I was thinking about the Thermalright SI-128, get a kick ass fan on it, and perhaps it would be almost as good as the holy "Tuniq Tower 120" ... err, perhaps not, lol

How come ur ambients are so low? mine is 42 c??

I presume you mean your idle temps are 42C.

Anyway, I don't think you need that big a case to run a Ninja. It fits into all the cases I have here (from cheapo no-name to Lian-Li)

yea but i dont mean the cpu i mean the northbridge

my cpu is idle 66 load 70
