advice on heatsinks

[ratdude747]

i need advice on finding good socket a heatsinks for use on a pIII coppermine cpu.

the case is a sturdy chieftec with 4 80mm fans inside, with a 5th attached onto the ps. i am overclocking the cpu right now from 800 to 826 using the stock cooler:



but mine has official intel sticker. thats as far as it will go

i am using an asus cuv4x -e mobo with 1gb ram:

Re: advice on heatsinks

I have a StarTech FAN370PRO (that's the model)
which I like. It holds a 60mm fan, which is bigger than most 370 heatsinks.
It was marketed for Socket 7 and 370. Used it on a P3-866 for a long time. I think I bought it from buy.com but that was a few years ago.

I've personally never found a socket A heatsink that would fit a 370 without being way too tight. I think they have a different pressure spec but also the clearances might be different. When I tried fitting an AMD stock hsf on a 370 I backed off because it was *extremely* tight. It would have broken the remaining hook on the socket I'm sure, and/or cracked the die.


edit: Found it at newegg. Surprised it's still available.

I have two the thermaltake versions of this. Important to put a good 80mm fan on it, and flip it around so it sucks air though not blow it into it.

why?

Re: advice on heatsinks

oh, and what do you think of the first one? as for the rosewill, it look a bit like overkill- i dont want to oc so much that i have to overvolt it (overvolting kills stuff)

Re: advice on heatsinks

I always put my cpu fans pulling air through and not into the heatsink for a couple of reasons:

Dosen't blow the hot air onto the nb/ram/vrm/caps, more air flow because the fins being so close to the fan cause less air to move through it, blows the hot air into the case so it is more easily exhausted by the rear fan.

The first one is more meant for small 1 or 2U servers. From the reviews it does pretty good I guess.

Re: advice on heatsinks

The Alpha PAL8045 specifically is a sucker, not a blower.
The point about heat on the VRM caps is well made.

<that's the masscool 5r057b3>
This one has a 60x10mm fan... I really don't trust the 10mm thin fans. I've never known of a good one that thin.
That StarTech I referred to earlier is a 60x20mm, I expected it to be cheap and die but it still works fine after ~1-2 years of active use.
But of course the heatsink is the most important part, as fans can easily be replaced later. The copper on that masscool might be nice to have.

<Vantec VA4-7245>
Looks like it might be good. I worry about how well it fits on a 370, but they do say it will fit that. Probably optimized for socket A though.

Re: advice on heatsinks

screw the vantec- soundls louder than hell i heard.

370forlife, does the one you mentioned have mounting problems? a review said it bent fins.

Re: advice on heatsinks

looking at the startech, that one looks small, just my thought

[gdement]

Re: advice on heatsinks

It looks smaller to me in the pictures than it really is. It's not huge though. Basically just look at a 60mm fan and you'll know the size.

It's probably most comparable to a thunderbird heatsink. It's bigger than my thunderbird heatsink but way smaller than a palomino.
Definitely bigger than the intel coppermine heatsinks I've seen. I've never seen a stock tualatin heatsink so can't compare there.
The main draw for me was the fan size. Most 370's are only 50mm, and I don't like small fans.

Manufacturer claims it will work on any 370 up to 1.4GHz, but I haven't tried it on anything that fast myself so they could be lying. Fastest I've used it on myself was a 1Ghz coppermine, don't remember what the temperature was.


I have that rosewill RCX-Z100 on my socket-A machine. I'm surprised if it will fit on a 370 without breaking the hooks off, but I could be wrong.

I'd love to find out about a 3-prong 370 heatsink that fits well. I could use one myself.

Re: advice on heatsinks

Found the startech and measured it.

The height is about 1" from base to the fan. The fins on the outside of the fan reach to about 1 3/8". Length/width is basically 60mm (2.36").
So yeah, it's fairly small.

It was a little tight on a socket 370 1ghz coppermine w/heatspreader, but the heatspreader makes it thicker so that was to be expected.

Mine came with the three holed clips, not just one holed clips, so it distributes the tension among the tabs more evenly to reduce clip breaking.

But I would bend the clip just a little to make it not-so-tight.

**I see the rosewill does come with the same three holed clip that came with my thermaltake verson***

Re: advice on heatsinks

370, what mobo, if u remember?

[ratdude747]

Re: advice on heatsinks

and, if i left the red fan on it, would it still work?

[370forlife]

Re: advice on heatsinks

That was on a Abit VP6, the fan would work fine, just be better if you got a nice 80mm that would suck air though not blow it through...

Not to mention the fan would be a good one for a case that only has 80mm holes that you want to put a 92mm in.

BTW, does your motherboard still have the stock NB cooler? They didn't have thermal paste on them, just rested up against it basically.

Re: advice on heatsinks

yes, but with the intel logo. i greased it lightly- just enough to lightly coat the die since more than that insulates the core and makes it overheat

Re: advice on heatsinks

hey, what about this one?

Re: advice on heatsinks

it said:

Socket 370 Intel CPUs up to 2.20 GHz!

damn now THATS overclocking!
