Best cooler for Dothan

[Vitality]

I think theres no need to use any better cooler for dothan than 7700Cu. Even 7000A-Cu could be enough. Cause Dothan won't heat so much, theres actually no sence to use any better cooler so far. I did understood that, after i installed 7700Cu. It's nice that now it won't heat so much, but at least with 1.6v there was no oc:ing difference, i think. :O Only lower temperatures, wich is very welcome anyway.
Maybe i could get some advantage with that cooler, if i try with bigger vcore, but i think it's unfavourable... I will someday try it still, when i get better memories.
I just wonder is it worthwhile to use vcore over 1.6?

Macci has just fitted a 9500 in this thread: http://www.xtremesystems.org/forums/...72#post1121972

So you can see it can be made to fit, and DOES improve the clock speeds
(Also looks great )

My Dothan 750 has a Pentium 4 heatspreader on top lapped good. Since this raises the total height of Dothan+CT-479 would I be able to fit a Zalman 9500 without mods?

In general, has anybody with a Dothan+heatspreader on top managed to fit any other coolers except those in the Dothan stickies?

Apparently these are very good for even mobile cpus. Why are they better than most heatsinks out thier ? They use the "Bolt Thru" method much more stable and better contact with the CPU.

They are extremely RARE now as Thermalright stopped making them i did however see 1 on ebay. ITs full copper and better than XP-90 XP-90C Si-120. Highly recommended by DFI street also.

bolt thru

dothan

not the most co-operative pair

anyways

The Coolermaster Aquagate, isn't exactly air, but priced around the same and easy to mount with the zalman mounts.

Just to let you know that I have just fitted a Zalman CNPS9500-LED cooler to my P4C800-E Dlx and it required only a few mods:

• Soldering of the CT-479 power connection directly to the adapter (as it snags the heatsink support bracket).
• Removing the CT-479 jumpers. I now run with no jumpers set. (This may or make not be required - I already had it done).
• Hack-sawing the supplied Zalman bolts in half (at standard length you'll be penetrating the adapter before you get good tension on the heatsink!)
• A CPU die shim made of four squares of Paxmate sound deadening material. (Highly recommended to avoid die damage)

With the above mods, the cooler will fit no problems using the standard P4 retention bracket.

Load temps have gone from 60 C to 43 C at 1.456v (real). Also, because the fan exhausts the hot air directly towards the case exhaust fans - case temps have gone down from 30 C to 25 C (21 C ambient).

Throttling the fan speed down to 45% with Speedfan when the temp is under 42 C yields a very quiet fan. Make no mistake though, at 100% this cooler is loud! However with Speedfan, this is only needed while hammering the CPU.

This cooler is so good that it can even run passively (fan stopped) for 40 C idle and 55 C load, at least with my case (Thermaltake Xaser III).

What is very important with these coolers (which aren't natively meant to fit the CT-479) is that you get good contact with the die. To test this, fit the cooler and boot the machine into the bios and use the hardware monitoring feature to check your temp. If it is over 50 deg, shutdown the machine immediately and reseat. If it is nice and low gently rock and hold the cooler in all four side directions (N, S, E, W). If any of these directions yields a better temperature, you haven't got good contact yet. You can also test a fifth direction by pushing the cooler directly down on to the socket, again, this should not yield better temperatures if you already have a good contact.

System spec:
P4C800-E Dlx (with 1023 bios) + CT-479 + Dothan 730 @ 2.6Ghz w/ Zalman CNPS9500-LED cooler
2GB Corsair XMS TWINX CAS3.0 in 4 x 512 DIMMS
HIS X850XT PE /w IceQ cooling @ stock
36GB Raptor main drive + 200GB Samsung Spinpoint store
Thermaltake Xaser III

Alright, I'd like to revive this thread with a few questions: is there anything (aircooling wise) that's better than the 7700/C77 that will just install?

Is there a way to put a faster fan in the 7700?

How difficult/expensive would it be to mod and to obtain the parts to mod a BT for Dothan use? Would there be much of a gain with Dothan's low heat output (~45-50W very well OC'd)?

Is there anything as easy to install as the 7700/C77 that costs less and still provides great performance?

Hmm don't know if you still want to know how to replace the fan but here's a guide for you

Hope it works for you

i have a TT Sonic Tower+120 Fan@Sandwich on my 740 Dothan. It fits without any mods with S478 mounting kit.
Performance is amazing. 2815MHz@1,7V with <40°C load.

Five-Seven could you post some pics? I'm really interested!

[Five-Seven]

np. Here are some pics. Hope, you can recognize something

Ah, very nice! Did you lap the bottom of the Sonic Tower before putting it on the Dothan? I see you've bended the power connector a bit. Overall all seems nice! Now to get my ST and get busy

[Five-Seven]

i didn't lap the bottom. yeah bend the power connector a bit, but that should be no problem.
