HS off Winchester :)

friend of mine took hs off winnie 3000+ and he's getting better ocing and lower temperatures with less vcore voltage needed :toast:

There a thread in the Best of AMD Stickiest. How much of an improvement did you get?

I knew the core was smaller but that looks half as small or more then a clawhammer.

Can't wait to see the results :up: What precautions do you take when mounting cooling to prevent crushing/cracking the core?

I saw another thread somewhere about a guy that removed the HS and lapped the bottom side of it and replaced the original thermal goo with AS5 and had good results.

Why aren't AMD and Intel using a copper hsf?, on a Prescott it would make a hell of a difference if you ask me.

I know copper is harder to machine but on the higher models (3.4ghz and up) they should use a copper hsf and a different cooler than on the lower models.

Atleast they should give the P4 EE SOMEthing extra.

Do you guys agree with me?

i dont understand why they use an ihs, isnt it meant to improve heat dissipation cos that just doesnt make sense at it just increases thermal transfers, i spose its just for protection of the cores is that right?

isnt the fx55 hsf copper bottomed? i'm sure i've seen a stock amd heatsink with a copper bottom

If I remember correctly the FX55 HSF's are copper bottomed with two heatpipes.

do you mean copper heatspreader, or copper heatsink? if it's heatspreader..then I know the P4 uses them for sure (I Lapped mine and it dropped the temps about 2c on both idle and load). The intel heatsink/fan assemblies are machined aluminum with copper slugs in the center. seems to be a popular design.

They're talking 'bout the ihs not the hsf ;)

The IHS is copper. Try lapping it..

Afaik they are also talking about the HSF and not only the IHS.

IHS's are copper, no way they would be as heavy as they are if they were aluminum.

They could do a lot better job making them and putting them on, though.

Eitehr way, AMD and Intell *DO* use copper heatsinks-- just the lower models have aluminum.

The heatspreaders are copper too.. even my wilamette IHS is.

the IHSes are copper? then why do they look aluminum?

Nickel plated

Exactly how much of an improvement did he get from doing this? :confused: I know its gonna be some, just interested in how much.. Could it be why winnies dont improve much using extremer cooling? :stick:

@Tedy - Very nice choice of tool for the job :toast: Prevents accidental damage to the components around the core ;)

IHS is copper ;) Just take a look :D

I doubt it, nc's do ok with extreme cooling and the ihs. I see no reason as to why the IHS would have anything to do with winnies being unstable at -0 temps. Maybe it is some weird fluke of nature though :slap:

ballsy man ballsy, how much of a total gain did he receive?

So would it be worth the risk to take the HS off , Lapp it and Re install it with AS5?

If you screw it up it can be fixed for RMA with seal string, superglue, and a razor blade........I know, I did it twice!

It is better to not have it on at all :slap:

4-7°c cooler now
oces a little better
needs less vcore for same settings

There is also a die size difference- winnies are much much smaller than newcastles or clawhammers and dont touch as much of the IHS.

Exactly how much?! 500mhz better? .1vcore less?
:stick:
03-27-2005, 07:32 AM
Jasonhk

Yea im ........guessing 50Mhz more ??
03-27-2005, 07:49 AM
TEDY

he told me around 50mhz more then before...

and 0.1-0.2 less vcore need

example

before 310*9 at 1.675v....now at 1.5+11%

you get the idea :=)

I just took mine off a few days ago and I'm getting much better temps -10c and better clocks at lower voltages with watercooling. 2800MHZ which was a little flaky before has been running prime 95 for 24 hours now. So, it improved my overclock from 1.53v@2700Mhz to 1.6v@2800MHZ and it runs -10c cooler.

I did butcher it up quite a bit and knocked off completely two of those surface mount resistors or whatever those are under the spreader... I wish I had taken pics because it looks like it's dead as a door nail but.... I put it back in and it fired right up as usual. :p:

Thats still 1.65vcore

:stick:

But, wtf does that have to do with how they do under -0 temps????????? That would have no influence IMO, :slap:

The spacer on the CPU's are not to transfer heat but to protect the fragile core.
03-27-2005, 03:22 PM
Nubius

They need to just go back to the original XP style then. Crush pads and an exposed core if people are obviously getting much better temps and OC'ing gains.
03-27-2005, 03:44 PM
Jort

is it worth with stock cooling?
doesn't it lower your cpu and so less pressure on the core and so almost no decrease of temps
