4400+ Remove HIS and XP-90C?

[slider99]

Hi!

I am, to be frank, quite unimpressed by my 4400+'s overclocking achievements, so far, and would like to get rid of the IHS asap (since I've heard it'll lower temps by ~10C). While deciding upon what WC'ing gear to get (most probably a G4 cpu block), my X2 is currently hidden under an XP-90C (all copper).

My questions are three...

1) Would it be a good idea to remove the IHS and use the XP-90C, through a cracking point of view?

2) Would getting an XP-90 (aluminium) be a better option with IHS off?

3) Or, would using the stock cooler be an even betters solution?

Thanks!

To be honest, the cores of the dual cores are double the size of a venice or double the size of a sandy, depending on the model. Everyone under the sun used high tension coolers on their Athlon XP cores and how many of them broke? I say take it off, get the good temps and just make sure you have the HSF held tight when you put those clips in (as the XP-90/120 series have a LOT of clamping force.)

[slider99]

Ok, I take it that your suggestion is to remove the IHS, and then just be a tad bit more carefull than usual, when applying the ~700g copper sink and hope for the best? I would love if you would elaborate on h ow exactly to ease pressure from the core while putting in the clips? Thanks!

Anyone else? Would this be a good idea?

IHS removal with XP-90 (http://www.xtremesystems.org/forums/showthread.php?t=71613) ;)

Thanks Lidocaine, good thread! Good info! Well, still, he was using the XP-90 (Aluminium version) weighing half of what my copper version does. There seemed to be another guy with a copper version in there too, though, who had done it. I'm hopeful. Gonna try it tomorrow I think!

Still open for more feedback though! :)

I wouldn't risk it unless you use something like the Athlon XPs had (rubber stand-offs)

[Perc]

deff use the rubber stand offs! to bad you dont have an old xp laying around (or do you?) you could steel the stand offs from that. as far as the heat sink goes just make sure you apply even pressure while installing it. i would also look at the sinks clamp and see if there is a way to bend the clamp just enough to loosen the pressure a little? that way you stand less a chance of breaking somthing seeings how those sinks have a real high clamping force! not sure if the 4400 is shipping with that new sink with the heat tubes? but if it is id just use that maybe with a bigger fan...


peace perc,

Thanks all for your responses!

IvanAndreevich > Actually, my older brother is using an old Athlon XP. Moreover, it was I who gave it to him, and now I'm planning to give him my old P4 that I've moved on to A64, so I'm sure I could get my old Athlon XP back!

Perc > Yeah, it's a newer HSF with heat pipes, and what looks to be a copper base. Am I adviced to use this one over my XP-90C and XP-90? (This would be better than an XP-90C with IHS, right?)

I don't recommend using the XP series with a naked core. I advise using a screw down type cooler, makes it way easier to apply an even steady pressure with little chance of wrecking your expensive chip. The zalman 7700 worked and for better cooling than the XP's you can use a Big Typhoon. The stock heatsink is not enough when OC'd anyhow and it is also a clamp on type....

[slider99]

How big difference would there be between the 7700 CU and the XP90, Big Typhoon (which I can't seem to find in retail where I live) and stock hsf?

Would any mod be required in order to make the 7700 CU fit without the IHS? Like lapping the XP-90's mounting bracket?

[Ugly n Grey]

The stock HSF is actually not bad, a zalman 7700 gave me about 4 degrees cooler at load than stock, but a Big Typhoon whipped the XP series by 4-6 degress and made a LOT less noise...this is all on dual core. On single core chips the stock HSF from a dual core gave the same performance as the XP's and Zalman did. But once you hit the duallies the higher thermal load makes a huge difference especially OC'd. I just found the Big Typhoon was the best at it but- be warned it's still not enough for any serious OC's. I say that because I found both my x2 AMD chips ran into heat problems before they topped out in terms of Mhz....Guys running on water are WAY better off when ocing these things...if they have decent water cooling...

No mods are required for the zalman as it ships with it's own under board mounted retaining bracket...no mods are required for the BT either.......

[slider99]

Well, I think I'm gonna try water lateron. Air till then, and I would have preferred a BT over the 7700 CU, but I can't seem to find it here in Sweden. Guess the Zalman will have to do.

Thanks! :)

I had the idea of removing the XP-90 mounting bracket, putting the XP-90 in it, and then screwing the bracket onto the CPU, sound like it would work?

[Ugly n Grey]

that may very well work out OK if you can ensure that the XP doesn't put uneven pressure on the core...

bad idea with a heavy clip on type sink. better with a screw down type.

[slider99]

Yeah, ok all. Thanks for your input! I think I'm going to go for the 7700 CU (possibly buying it tomorrow), since it seems to be screw-down type. Would I still have to use them Athlon XP bumpers, or can I go without them with the Zalman?

hijon89 > good thinking. might work, but i'd much rather go the safe route. still, nice idea indeed.

I put a neoprene shim I cut out of some packaging around the core just to protect the exposed elements under the IHS... On a Vennie I don't even bother to do that, I just mount the zalman on top.

I went at it brute force. Bent all corners downward...doh!
