Ofcourse this is all academic cause who knows where that sensor is and is it really measuring case air or is it being affected by some nearby heat source.


Proably isn't helping much that my raptors are heating up the intake air before it gets to the CPU area, and the air is much warmer at the bottom of the case directly in front of the raptors and below the 6800GT.

I'd like to avoid water cooling since I prefer to keep my PC on at all times.

??? I don't get that. My comps always on and watercooled.

I would just be afraid it would spring a leak or something while I wasn't around, I've never done water cooling before, but getting awfully tempted to.

I've decided to give liquid cooling a try. I went with the Thermaltake CL-W0005 BigWater 12cm since it's a complete kit and seem it will be a farily easy setup for my first water cooling attempt. Wish me luck, I let you know how it goes, should have it in a few days.

Good luck but something still isnt right if you're idling and hitting High temps with xp120.

I have my 3.0E overcloced to 3.3 w/ Vcore at 1.40 and im idling at 37 and Hitting 45-48 on full load According to my Asus temp probe. Even its under by 5 degrees, add 5... Idling at 42 and hitting max at 50-53 is well in the range of the Prescott.

I even had an OC of 3.6 running 57 full load. Somthing's fishy is all I can say. wrong temps shown or XP-120 not doing its job right.

with a properly setup watercooling system, leaving it on 24/7 shouldn't be a problem. i leave mine on all the time now since it's much quieter ;)

That s nice!! at 1.42v then you probably could get more the 4.0ghz...Have you tried for 4.2-4.3ghz???

I think it's really too bad that you paid so much for your 3.4e when my 3.0e runs at 3.75 with a little voltage. :( Luck of the draw I guess. I am moving to water, though, it gets up into the sixties under load at that overclock. Why don't you want to move to water?

Sorry dude, Prescotts are shit.

Even my brother sold his Prescott to go back to a 2.8 Northwood, said it pushed the mobo's voltage regulators too hard.

He's now running a 2.8 Northwood @ 3.7Ghz with watercooling. :)

Well, perhaps that's just so that people don't unnecessarily spread it over every surface that they see. I'm still of the old-school thought of TIM application, to spread it evenly over the entire contact-surface, but very, very, thinly. (In fact, I don't think that using AS5, compared to a properly applied layer of "generic white thermal paste" should make all that much of a difference, 1-2C at most.)

That's pretty good. I've seen 2.8C HT Northwoods with much worse temps.

Some silicon is just better than others. Especially considering the high leakage currents of the Prescotts.. I'd say he just ended up with a poor-quality chip. Based on everything that I've read here, there appears to be quite a bit of variance in terms of temps. (But since HSF/TIM/ambient temps factor in strongly too, I guess I shouldn't use anecdotal reports to make generalizations about the CPU specifically.)

I kind of wonder about the quality of the surface-machining of most heatsinks and the IHS too. I've rarely ever seen one factory-stock with what one could call a "mirror finish" on them, and some of them have appeared quite rough on the surface.

Dude if you want quiet and cool it can trivillly be done with AMD 90nm on air.

You can 5V all your case fans. Get a 5V 120mm nexus for thermalright..get a silencer on Vcard..and a PSU with 140mm turttle fan..

You can Mad OC and still not hear from 5 ft away...

Sell that p4 setup quick, while it still has value, before new version comes out.:)


the only reason I still use water is video card and it's a carry over from hot arse athlonXP setup which was almost like a presscot ..plus I don't like to hear comp on at all...

I already ordered the water cooling kit, so I'll see how that turns out before I completely give up. My rig isn't very loud anyway, the fans on the video card are the loudest, since I am using 120mm fans for everything else. In any case I prefer to have similar components between my main and backup rig in case anything goes wrong it's much easier to troubleshoot if I can swap CPU's and motherboards.

Water cooling kit is out for delivery..should know how well it works before I have to go to work.

for the price of that watercooling kit, you could have gotten an Athlon64 and motherboard, and re-used everything else......

I do a lot of multitasking, so the hyperthreading is an actual good benifit to me. Besides, water cooling is now installed, and no more heat issues. Went from 70-73c under load, to 48c under load..no more throttling for me. But it was definatly rediculous to have to get a $160 water cooling kit, to cool a $230 proccessor..

Load temps go to between 70 and 74c weather underclocked or overclocked. I have removed and re-installed the heatsink and re-applied the thermal paste 5 times, and always get the same results. Gets up to 70c, and thermal throttling kicks in. My 3.2ghz ES runs at about 63c max at 3.6ghz(highest stable OC) on the same motherboard, with the same heatsink, and running at the same temp on the gigabyte motherboard I moved it to, with a thermaltake jungle 512. The 3.4 runs stable at 3.74ghz, but what good does it do when it's throttling even when underclocked...short of water cooling I don't know what else to do with this crap chip..

this is proof of how much prescotts suck
my amd gets up to 52C load with stock cooling and AS5, and it runs circles around your P4.
new requirement for dualcore p4s: phase charge :p

I'm not sure "runs circles" is the right term. Remember, that chip is overclocked to 3.91ghz...

And I found that my CPU @ 4.0ghz is roughly equivalent to an A64 3800+/A64 4000+ when it comes to gaming.

The A64 4000+ is rated against a theoretical P4 4GHz. But I still doubt a P4 @4GHz will keep up with an A64 4000+ with regards to gaming.

With any equivalently rated A64 & P4, the A64 smokes the P4 in gameing, usually by a good margin. ;)

What kit did you buy? I'm cooling a 3.2 prescott @ 4ghz with a custom watercooling system and my load temps never exceed 45C. Mind you I did some heavy research in watercooling and built the best possible cooling system for less than $150.

You skipped water :p

Your AMD system is still more than a minute behind my CPU when it was running 3.95ghz in SuperPI and I never patched my program. My AMD record is 2.6ghz with an old 3000+ clawhammer and it never matched this intel system in performance.

This is overclocked, it'll run faster than a chip running stock 4.0ghz.

I'm not so sure about that. The RAM latencys have to be raised to to run that fast, which nullifys the higher RAM speed.

All things being equil, the higher bus will not make up for the P4's large defficet against an A64 in games.

That's cool. Theres some definite advantaqes from water you can't get from air. Like real quiet if you tweak out.. get a GPU water block too...start undervolting case fans etc.

It is much much quieter than before, the 120mm exhaust fan on the radiator has a fan control, so I can make it quiet. I can actualy hear my raptors now, I could never hear them over the fans before. Thanks to my case design, I actualy have a 120mm fan blowing in to the radiator, and the fan that was on it blowing out, with the radiator mounted on the outside of the case. And it was suprisingly easy to set it all up to, and should be able to keep using it with future upgrades as well.
