What heatsink would be ok for me

[snowdog]

Hi,

I wanted to ask if anyone can tell me what cooler is ok for a (overclocked) pentium 4 socket 478 prescott, i need a cooler that can keep it under 50 C when its under stress, as at the moment i have a Zalman CNPS7000B-CU cooler its ok for stock speeds and light overlocking but i cant increase my vcore higher becourse my cooling isnt good enough.
I need a cooler that can keep my cpu below 50 C while runnung @ 260 mhz fsb (from 200), so a 30 % oc (from 3.00ghz to 3.91ghz), and a vcore of 1.5v
My present cooler lets my cpu be 60 C when under stress (@ 1.45v vcore) so im araid to increase vcore mroe but i need to otehrwise my pc is unstable becourse of vcore voltage drop when under stress.
So whats the best cooler i can get for socket 478 my price limit is 50€ so about 30 quid?
Also is 50c possible as a p4 prescot really produces a lot of heat when overclocked much more than a64's.

Thanks in advance

yes but can it take the overclock? as when my cpu isnt overlclocked its a lot cooler around 50 ish when stressed and 30ish when idle (now on oc: 40ish idle 55-60 (air temperature dependant) when under stress, will that cooler really keep my cpu 50 c max?

its the best hmm ok...
ill try looking for it where i can get it the cheapest together with shipping costs...

thx everyone for responding feel free to give me more advice

EDIT: ive just read the thiung is really heavy, so my next question is if my mobo will be able to carry that huge weight, or if theres anyone out there with a broken mobo becourse of hs (or if tehre arent any), please tell me if its safe (or not)
(I have a Asus p4c800 Deluxe).
