New System.. Overclocking D805 need cooling suggestions

I have a question about the case and cooling though.... The one on the list was originally a joke but what suggestions do you have for case and cooling. Sound isnt an issue but performance and durability is a must.

Do not get an 805, especially now. There is no reason to deal with such a pathetic CPU. The crippled FSB and half the cache just kill it. Look at the D820 for a few dollars more or the D930. Both are still highly overclockable but run on at 800MHz bus vs 533 and the 930 has a full 4MB cache.

Actually, the slow FSB helps make it such a stable overclocker. OC'd to 4GHz, the FSB is the standard 800MHz, so no need for fancy OC memory.
That said, the 805 is really best for a ghetto OC rig, with bargain-basement components. If you're going to spend real money on a PS, gfx, etc, get a MB that handles Conroe, and use your 805 CPU money toward a core2 CPU.
Bottom line: if you're spending more than $500 on the system, it's best to skip the 805 and go to core2.

 

[Mondoman]

As for cooling, looking at your original board choice, it uses big hs for the northbridge and VRMs that depend on airflow outward over the MB from the stock Intel CPU hsf. If you're going to be using an aftermarket cooler (almost all of which don't blow over the MB in all directions), you will at least need to add a small fan to the northbridge hs and a small hsf to the VRM heatsink. Even with that, you may need to add one or two other small fans to the area around the CPU for stability when OCing.
Bottom line: not a good MB choice for OCing.

there is something wrong when your cheapest component is the cpu.....

get conroe...ur bottleneck easily is going to be your oc'd 805 from day one

If your serious about the 805
For moderate overclock Zalman cp7700 will work very nicely and blows air around vrm area .
for more extreme overclocks try the thermaltake CL-W0075 or the SE in my sig.

I have to slightly disagree with the suggestion of the thermaltake bigwater kit. I built a system for a friend with that cooler setup and it has one of the crummiest pumps I have ever seen and it's cooling performance wasn't all that spectacular (not to mention a lot of evaporative loss and acrylic topped waterblocks have been shown to corrode and leak more frequently than could be considered healthy).

If you really must get a prebuilt watercooler kit (versus assembling the various, pump, resovoir, tubing, barbs, waterblock, radiator, etc. individually) then I'd splurge just a little bit more and get a swiftech H20-120 premium. I've seen them selling for around $175 at sidewinder computer

I use the swiftech apogee waterblock and MCP 665 pump in my system and I couldn't be happier with it's performance and reliability.

EDIT: One caveat, the bigwater system I used before wasn't the SE; it looks like thermaltake has changed their pump/resevoir setup which changes my opinion from "thought the pump sucked" to "have no idea how good their pump is now"

 

[kwalker]

All is well on the cold front .
the pump is fine .
the earlier models were not all that great and if your going to keep any liquid cooling system for extended piriods of time you must change the coolant every 6 months minimum.
or corrode it will.
any system can fail and it pays to shop around.
I have back ups for just that reason.

 

[nikolokolus]

everything you say above is right on the money . . . I just remember he called me up 3 months after we put the thing together wondering why his comp kept shutting down ten minutes after boot, I went over there popped the side of the case off and his cooling loop was down to about 20%

I'm glad to hear Thermaltake has refined their bigwater system; I've long been a fan of their air coolers (if a little loud) and it's good to know that his was probably an aberration.

The stories of acrylic corrosion mostly stem from posts I've read on the extremeoverclocking.com forums when people added water wetter to their coolant . . . plus just people warning people off of acrylic . . . then again it's the internet where FUD, hearsay and wild speculation rule.

 

[kwalker]

have your friend pick up one of these .
the SE comes with this tank that fits in drive bay

that's similiar to the swiftech resevoir I have in my own system (makes topping off MUCH easier), I'll have to point this out to him, plus try to convince him to ditch that godawful pump he has now.

 

[kwalker]

have you seen this one?

your friend could solve two problems

True enough . . . though he's a cheap bastard, so for him barely adequate is usually "good nuff," I tried to warn him him off going with 1/4" ID tubing but he didn't want to hear any of it <shrug>.

Personally I think my resevoir was a waste of money in my own setup (though the resevoir on rails in my antec case makes refilling a breeze), The next time I do it, I'll probably just run a 'T' at the highest point of the system and attach a foot of Tygon and refill it from there.

 

[kwalker]

you get what you pay for.
he,ll cry on your shoulder when all the smoke comes out :lol:
3/8 tube minumum ....but who are we?
that Swiftech Pump & Reservoir is my back up.
you only need it when you dont have it.
