Heatsinks?

Post by theEMP »

So what are the best heatsinks to get for a (super) socket 7 motherboard? Do most socket A/370 coolers work on 7 boards?

How about a quick review of some heatsinks that you use folks? :D

I guess cooling isn't an issue on K6s and super7s.... :lol:

Come on folks what kinda 'sinks do you have sitting on top?

I have one in mind if a A/370 cooler will fit...

Almost all Socket A and 370 coolers will fit, as long as they use the standard method of attaching via the notches on the socket. Socket A coolers which attach via holes on the motherboard will NOT work with Socket 7.

The one Socket 7 rig I have running here (VA-503+, K6-III+ 450@550) is using a six-year-old GlobalWin FOP32.
FIC VA-503+, Rev. 1.2, AMD K6-III+ 450@550MHz, 80GB Seagate ATA-100, 3dfx Voodoo3 3500 TV, TB Montego II Quadzilla, Win98se, 384MB PC100

Compaq Presario 1273, AMD K6-III+ 450@400MHz 1.8v, 40GB Samsung 5400RPM, extremely hacked Win98SE, 288 (yes, 288!) MB RAM
(Also an AMD FX-8350, which does the heavy lifting these days...)

thanks for the tip JSC, I'm still in the process of reading the whole super puppy thread :lol:

(seems like they should run puppy linux doesn't it :lol: )

@theEMP

You have to be careful with your selection of cooler as most socket 7 boards are crowded around the zif socket with capacitors.

I have managed to get a Globalwin CAK38 cooler onto most Socket 7 boards I have but anything with a wider base you can forget.

This big copper cooler was just what was needed for o/cking on my Asus P5A 1.04 board. With this cooler I can o/c to 630Mhz(105x6) or 617(112x5.5). I find that you have to keep the cpu temps below 45C to prevent crashes. The P5A board tends to really shove the juice into the cpu as it has a lowest cpu core voltage setting of 2.0V and I/O voltage of 3.5V, which makes it run a bit hotter than most of the other boards I have.

The "best" heatsink/cooler you can get is one that removes enough BTU to keep the CPU from overheating.

Anything more is a waste of money and space.

Remember that the heatsinks job is to pull heat from the CPU core and thermally stabilize it, while the fans job is to remove excess BTU from the heatsink.

well the heatsink I have in mind is a coolermaster x-dream II ( http://www.geeks.com/details.asp?invtid=HAC-L82&cat=FAN ) but replace the fan with a high flow thermaltake smartfan II.

It's got a copper core and is well thought of by several socket A folks. The aero7lite uses the same heatsink base to it, but with a blower fan on top.

Looks overkill to me...but whatever floats your boat.

The socket 7 mounts are identical to the mounts on a socket 370 zif. If you use a cooler like the x dream you will either have to change the spring mounting clip to a single mount or saw the triple mount down to fit. Like I said you will find that most socket 7 boards just will not have that much room around the cpu socket. Some boards have caps almost touching the zif soket in the most inconvenient places for mounting big coolers.

On most socket 7 boards running a K6plus chip at 550-600Mhz an aluminium cooler like the coolermaster DP6H51 should be adequate to keep it cool.

Unfortunately my baby-atx hot-591p hasn't temp monitoring, but I'm using an old Coolermaster DP5-6I31C-A1 (http://www.amd-SPAM/images/dp5-6i31c.jpg ) with an old socket 7 clip that keeps it exactly in place. The original one was dangerously strong, so I replaced it. It's 6x8x4cm with a 6cm fan support, no copper on base. If I still had any tbird stock cooler, I'd use it instead, as it's the same thing but with a small copper lug.

It came with an 6x6x1 delta EFB that had a broken blade some years ago, so it still has my replacement fan, the same screamer that came in the full rated TT's Dragon Orb3 but in framed version, sold by TT as an upgrade to their coolers years ago. It's an 6x6x2.5cm Everflow fan, rated 38CFM, 7K rpm, 37db rated of an awful whistle (in a test 61db was measured...), way more disturbing than my 42db rated Deltas!, but tamed to 7V (3.5K rpm) which is very acceptable. It still makes a LOT of air pressure (more important than CFM when talking about CPU cooling), way more than the AVC fan that comes with amd coolers at 3.0K rpm.

It doesn't touch any caps, but due to the socket being too close to the AGP slot, I can't use any graphics card with tall components (except for memory chips) in the back end. On other board, I was using it with an 6->8cm adapter without clearance problems.

Still, I can prime my K6-III or K6-2+ for over 12h and it's still cool to touch on the base.

The biggest/badest thing that will fit that mobo! :twisted:

Personally, I go for nice meaty PIII/Athlon Class heatsinks... though the beastie below (Thermo-Engine) is even BETTER thanks to it's 60mm Delta screamer! :D

I guess I'm at odds with KachiWachi on this one, as IMHO factoring future requirements/performance into a thermal application is a good thing! I even use an Athlon Heatsink on my Cyrix MII, summers get really hot here 35 ~ 42c ;)

With forced air only, you can NEVER get the component temperature below that of the ambient air temperature. In a perfect world, the best you can do is make the temperatures equal.

So all that will be required is a heatsink/fan combination that can perform this operation. Anything more is overkill.

Thanks.
