Hello,
I currently have a Dragon orb 3 in my system. And im trying to get the system a bit cooler. Im runnning about 48 C idle and 55 max or less full load. I have plenty of case cooling (2 120 mm sunon 2 92 mm sunon 1 80 mm generic) and try to keep the house temp down but I still feel its high (expecially since I have an asus board which im told the onboard temp gauge reads up to 5 degrees lower than the actual temp is.
My roomate has a global win cak-38 and he loves it. he has an oc 1ghz to 1.2 and only "1" 80 mm case fan and his runs about 48 with load (which really ****ses me off since i have a better cooling situation than he does) so I was looking into heatsinks and i wanted to try to get one like his, since my board is not compatable with those really nice ones from Swiftec. I saw the Global win cak-II38 (newer model) and the older cak 38. as well as the thermalright sk-6. I have seen reviews for the cak38 and sk6 but none for the cakII38. I was wondering what the opinion is of this fan versus the others if anyone has one or has expearence with one.
If anyone has any other suggestions for a good fan or cooling (other than watercooled. too much for me right now) id be intrested to know. Thanks !!!
I have a cak38 and don't like it too much. I will see how it compares to a glaciator2 witch is being shipped right now. It should be here in a couple more days. I can't handle the noise and I think it will cool my 1.4 better.

i think i have seen one review of the cak 2 but it is not as good as the sk6, one point worth considering is that your pc and your roomates pc are probably using built in heat sensing stuff, which isn't relyable and can be off by up to 10degrees celcus

Thats true, Im thinking about getting a temp gauger from radio shack. Somone once reccomended it to me I cant remember what its name was thought. Oh well ill ask a guy theyre.
I did like the stats on the Sk6, I just did not like those small pieces of metal being the only things holding the can onto the heatsink.

Get Glaciator 2 and sleep peace :)

I thought about a Glacier 2 but one problem. Same with swiftec.
Notice: There is a compatability problem with the Asus A7A266 motherboard. A capacitor near the DDR RAM slots interferes with a proper sink mount and is not recomended
I have that board. Wonderful board. But that capacitor makes 2 of the best heatsink contenders useless on my machine.
as far as noise, it doesnt matter. the 2 120's and 2 92's produce a LOT of noise. the little 80 adds a bit. (Sonunds like a jet enginge starting up.) But I don't mind the noise. im more worried about the performance.

So im back down to sk6 cak38 or cak II 38 unless somone has a better (non watercooled) solution.
Heard a lot of good things about sk6, just the way its locked down (the fan) doesnt look as secure as other fans.
Does anyone know of anything that would make one of these 3 fans (or like i said other fans) better than the other that I can use.
Permitting that it will fit on my board. Or should I just stay with the dragon orb 3?

dont worry about the fan not being secure, it is, the sk6 is the best that you can get on your mobo at the moment

The Fop38 out performs both the CAk and the WBK 38 (head over to overclockers.co.uk) he re-ordered it to make sure it wasn't fault as well. The CAK IS S***.
The SK6 even beats the Alpha PAL 8045 and maybe even the Swiftech 800grams one.
Why? Because its SOLID COPPER and has a surface area of over a Foot!!!!
*Edit/The SK6 doesn't beat the Alpha or the Swiftech, there about 8C better, I had to much :beer: that night!*

Umm... no. The SK6 is a good heatsink but it doesn't beat the PAL8045. I know. I have both. What most people dont know is you should probably skip right to using 2 washers in between the springs and the screws. I also have a Glaciator 2 sitting here, waiting for me to test, so I'll run a little comparison. The SK6 is definitely a good heatsink for those who don't have the 4-hole mounting system (P3's and some older Athlon boards) or do but can't get that HSF on there. (MP boards)

Your idle temps leave a little bit to be desired. Just out of curiosity, what kind of CPU are you running? AMD, or Intel? NO THIS NOT A MAUFACTURER FLAME! It's common knowledge that AMD's run hotter than the Intel's normally. In either case, 55°C is way too much for an oc'ed system. But if it's an AMD, you're definately in the danger zone. I got better cooling with a 933Mhz PIII HS wih a 1Ghz Intel fan than I did with my orb, on my celly 800.
VegetaQ - The DOrb3+ Copper is actually better than the CAK38 & here is the proof (http://www.overclockers.com/articles373/). Did you take out the thermal pad that it came with? That will actually raise your temps quite a bit, 10°C or so, if you leave it on. The monitoring software could also be faulty. If you really want a better cooler then go for the SK6 but make sure all the fins are soldered properly to the base & that it is indeed flat. They have been experiencing low quality problems as of late & it would not hurt to check.
nick_cw - Who told you that the SK6 was SOLID COPPER?! Wrong information there. The fins are soldered to the base.

Hey sickboy, is the Pal 8045 quieter than the sk6? I have an sk-6, and I'm looking for something quieter. Whatever fan I slap on the sk-6, it seems to have a whiney noise to it.
I understand that the 8045 ships without a fan, and the way I figure it, if I put a fan w/ at least 38 cfm, it should about equall my sk-6 w/60 mm sunon.
I'm looking for the absolute quietest that I can get without going to watercooling.
thanks in advance,

I think i'm right on this occasion heres the pic of it:

The Alpha Pal 8045 has a copper base with Alu fins and the GIGANTIC Swiftech MC-462 (nearly a KG!) has a solid copper base with ALu fins soldered to it.
The SK6 can perform with these monsters as i'm sure its pure copper.

Is the Alpha Pal any good?
Maximus Nickus

or the Swiftech?

It's on the second paragraph;) Also there have been a few threads discussing the low quality of the SK6 with one of the problems being that the soldered fins are not connected properly. Here is a bigger pic that shows the fins connected to the base & a little bit of solder.
http://www.overclockers.com/articles394/therma1.jpg
The Dynatron DC1206BM-O (http://www.overclockers.com/articles436/) is almost a solid copper heat sink. The fins are shaved/skived from the base.
http://www.overclockers.com/articles436/dyna1.jpg
Here is a close up of the fins;

A comparison of the Dynatron & SK6 fins;
http://www.overclockers.com/articles436/dyna6.jpg
The SK6 is still better but not because of the solder joint but the since the high fin density of the Dynatron design you really need a strong fan, maybe an 8000rpm 50CFM delta, for it to cool better that the SK6. Equal fans the Dynatron loses but go with a totally load & unbearable fan then it just might be a different story.:beer:

They may be soldered but it doesn't say there not copper!;)
Anyways you know of a cheap:eek: place I can order the Alpha PAL 8045 from? I read some reviews and it beat the Swiftech with a 65cfm/80cfm delta on it.
www.sidewindercomputers.com have it yet they seem reluctant to state shipping costs and accept international orders.
You see if I can find a cheap place I won't have to dis-assemble my Board if I have to get it at a later date.

Well I have ordered from Bart (http://1coolpc.com/home/) & have been happy with his service. If you e-mail him he will reply within 3-4hrs usually & will give you the shipping costs. May not be the cheapest but one of the most reliable IMHO. $40.00 w/o a fan.

The Alpha out-performs the Swiftech don't it?
I'm just about to order the Alpha should i get the 65cfm delta? or the 80cfm (where can i get it from?) as i want the best performance regarless of noise, wat diff in degrees will these two make?

If memory serves, the 80cfm is about 10dBa louder than the 65cfm. If that's right, then as I recall that means it should be close to twice as loud. I've seen review sights that had the 80cfm on hand but refused to use it because of the noise. It would give you extreme air cooling, but you might want the computer in a different room. ;)

Wait a little longer for the MCX462. The 8045 trails the old MC462 a little but the NEW MCX462 is the hands down winner by a mile(exag.:D). I suggest you e-mail delta for the closest distributor that they have. Don't you want the 105CFM 80mm?:D

I already have 2 delta screamers and 6 ys-techs @ 40db each, also loads of other fans so it already makes a racket.
The Question is how much of a difference does it make to the 65cfm one? Degrees C?
If it makes a big diff then i''l buy it, if not ill get the 65cfm one.

Thank you everyone who gave me information about the heatsink info. This and everything else I can see leads me to the MCX462 By swiftec. It was the one I wanted but It wouldent fit my board. But according to the manufactuers page
Motherboard compatibility
MCX462: Fully compatible with all* socket A motherboards compliant with AMD specs, in single or dual CPU configuration. The new patent pending geometry is such that it fits entirely inside of AMD component height restriction zones. This allows clearance for capacitors located in areas close to the socket which are non height restricted by the CPU maker. Click on picture below to enlarge
So hopefully This will work out well. Once I get this I Might be able to get the temps low enought to get a stable overclock. Thanks for everyones time and information.

the cak 38 is awesome! I am @ 1.2Gig and runnign 100F undder load!!
now that to me is impressive... if you have a CAK you dont want - i'll help you get rid of it!
I got my glaciator2 and this thing kicks a**. I overclocked to 1470 just to see how much better it is than my cak38. Woke up this morning and I am sitting pretty at 44 degrees while folding all night. I could barely get 45 at idle before at 1400. well now to try for 1500.

E-mail Swiftech before you order it and ask them if they will garauntee that it will work with your mobo and if it doesn't, that they garauntee that they will buy you a new HSF that will work :)
I like the way Ed thinks :P

HEHE. I should email them. But the only thing is their heatsink is the most expensive one. Id probably loose money if they sent me somone elses heatsink at a lesser price. I have seen that some people have just taken a Dremel to cut into the sink. (Most of the time its just a capacitor too close to the hsk) and if you take a small piece off of the corner, it usually fits. But it voids the warranty.
