i cannot decide which hsf to get. it will be on an epox 8kha+ board with an XP1800-will be overclocked. the alpha site says that the pal is compatible with the board, but it will touch other components, maybe damaging them...:o
does anyone have any suggestions?

I can vouch for the Volcano 7+ with running a 1800+ @ 2000+ on a 8KHA+ board very well. :smokin:

yea the volcano 7+ would proabably be the best choice....or you could get an thermalrite AX7 which performs about the same but looks much better(in my opinion)....or if u wanna be really crazy like me....u can buy the mofo of a HSF Swiftech mcx462:afro: ...and whack a 69cfm delta on top.....even MY ears can't cope woth the 80cfm
:cheers:

btw it also depends if u plan to voltage mod....all 3 will perform much the same at 1.85 volts but crank up the the voltage to 2.2v and will see that the swiftech handles it better due to it's sheer heat-absorbing properties...gotta love that sexy beast:afro:

of course this was just one review i read and may not be tru but still....think of that sexy sandwich-thick shint copper base and those beautifully crafted hellicoid gleaming aluminum pins...*drool:cheers:

IMO, heatsinks designed for performance MUST be solid copper. I would suggest something similar to a OCZ Gladiator, if you can find one on the market. If you don't know what it looks like do an image search on google for OCZ Gladiator

I've got an OCZ Gladiator myself (It goes under another name, but i can't remember...). However, if the Volcano 7+ is an option, go for this instead. It's much better than the OCZ....

Beffy a Powercooler PCH137 is what the OCZ Gladiator is for the simple fact that OCZ bought these and repackaged them with their name which is all any OCZ product is, someone else's product under an OCZ name. ;)

fancy that happening.. < / sarcasm>

I knew it was a Powercooler something.. :D

If anyone is thinking of buying a heatsink/fan for a P4, don't buy a ZALMAN CNPS 5500Cu.

The main problem is the lack of it's cooling capacity, it just doesn't work because the main heatsink section of the 5500Cu is oval where the heatspreader on the Pentium 4 processor is square and is slightly larger than the base of the CNPS5500-Cu heatsink, so that means that parts of the heatspreader was left uncovered and that can result in hot/cold spots on the processor and thus reducing it's effectiveness. Not a good design at all.

Hope this helps someone not get caught like I did. :angryfire

Powercooler PCH137
SWEET! So it's still on the market?????

Anyone have a source?

Well they're still being sold here in Australia so I would imagine that someone in the US would still carry them. :smokin:

Zeradul, heatsinks disigned for performance don;t have to made out of copper..y is the alpha PAL and swiftech made with a copper base and aluminum pins? bcos copper absorbs heat and conducts it better while aluminium dissapates heat better:) .....incidentally aluminium is much lighter. cheaper to mine and cheaper to machine....lol imagine if the mcx462 was all copper....i'd pay even more than the ridicoulas $175 when i bought it:cheers:

Just a follow up on my problem with the ZALMAN CNPS 5500Cu heatsink/fan.

ZALMAN has offered to supply me with a new CNPS6500B-AlCu setup to replace the 5500Cu. I sure hope this one works better. :clap:

while aluminium dissapates heat better
Nope. As far as heat sink construction, aluminum has NO advantage over copper other than density. (and price if that counts... AL is cheaper)

If they thought they could get away with their design made out of purely copper, they would. And it would perform MUCH better. As you said, copper is much more dense, and therefore the popular (or at least expensive) design you speak of simply would weigh far too much.

The ONLY way that the design you mention performs well is due to the MASSIVE CFM capable fans they use. A very popular Alpha PAL model (not sure on exact model #) only defeated the OCZ Gladiator by half of a degree in anandtech's most demanding benchmark, and it had a fan capable of MORE THAN DOUBLE the CFM. (not to mention TRIPLE the retail price (!!) )

reallY hmm....well all i know is the swiftech mcx 462 is still the BEST performer compared with any other cooler using the same fan....weather it's a 80cfm or a 30cfm
in fact all the best performing ones such as the ax7 and alpha PAL alos have aluminium construction.....although the volcano 7+ is all copper and almost as good as an alpha PAL...although i have to admit i don't know enuf aobut the gladiater to to make any comments on it...

There are a few reasons that design is popular. It looks cool. Its easy and inexpensive to manufacture. Using purely massive amounts of CFM do cause it to be effective, (even in the average geek's less than perfect air flow situation) It does this with added size, and therefore added surface area.

And with that said, I highly doubt any design that you mention would outperform a gladiator on a low CFM scale (quiet) Somewhere in the range of 20-25 cfm, I doubt any current heatsink can outperform a gladiator.

The Gladiator is basically a slightly smaller version of the Volcano 7+, except it does not have the inefficient gap where the clip is on the volcano.

I was thinking about this some more last night, and if you think about what you said, I think you will agree. Conducting, and dissipating are the same Thermodynamic principle. There is no difference despite one instance being metal to metal, and one metal to air. And in that case, copper is 35% better heat conductor. Better than everything, except silver, which out performs it by about 1%.

The next step in heatsinks is to design them with ways that duct the air through the apparatus, not just force onto the aparatus. Think of melting an ice cube that sits on a table, and pointing the fan down over top of the ice cube, versus making a tunnel around the ice cube, and flowing air around it. This is another proven and implemented method used by all air conditioners, refrigerators, etc. (there are a few refrigerators that are exceptions to this)

The trick is to design a method that isn't huge and still can support itself by the little socket clip...

lol ok you have me convinced about the benefits of copper....:afro: ...btw how much does the gladiator sell for anyway?

I just got the Thermalright AX-7 with the Thermal Take Temp Controlled Fan from the Volcano 7....its great...its at 2700rpm and my cpu is at 1333 right now...but its very quiet...im coming down from a Delta fan...so its a great relief...im probably going to get an XP CPU just for the cooling reasons...probably an 1800+...anywayz...just my 2 cents...peace

Another point that I didn't mention in hopes of keeping it simple is this. Alpha PAL style HSF's are purchased by those who plan to OC to the max. Noone else buys them (basically) And so these heatsinks are designed to deal with a very high rate of constant heat, and these designs do thrive when lots of heat is involved, mainly due to their surface area.

They definatly aren't bad, they just aren't worth it. Gladiators used to retail for 28$ which included a grill, a 38cfm delta 60mm, and free OCZ thermal paste... you could get just the heatsink for 18$ i believe.

OCZ has had some problems, which is a long story, and I don't know the entirety of it, but apparently 'Gladiators' are still for sale under their 'real' name...

For experience, i'd like to say that thermaltake has done a pretty darn good job with this cpu cooler. It's a good cooler keeps my 1.4 not clocked under 40 degrees constantly, very good cooler if you ask me. I used to have the WBK38, it sucked my cpu temp was around 50+ i can't remember though maybe even higher :D

lol dun talk to me about wbk:D i had one....and in the middle of summer i got 58-60 degrees load:shoot:

That's because it wasn't applied very well remember...:p

But your right, it did suck pretty bad :D

lol yea! and when i tried using the cheapo thermal paste that came with my mcx462 it wouldn't even boot at stock speed..wierd eh?:shoot:

although to be fair i don;t tihnk i cleaned away the thermal gum properly from my wbk:afro:

oh yea and i think there was a bit of arctic silver left over as well:cheers:

hehe not a good idea to use cheapo thermal, i had a friend who did, and this stuff was the king of cheapo it fargen set in the bag it was hard as concrete. I have nfi what it was made of, anyways i let him borrow my arctic silver. All good now :D

chisholm
05-15-2002, 07:00 PM
lol that cheapo stuff looks like arctic silver but sure isn't arctic silver...it as really hard to apply....like semi dried superglue...and man does it stain...i still got stains in my sink from when i "flushed" the crap down the sinkhole :afro:

Well, Zalman sent me a nice new CNPS6500B-AlCu and it is a much better cooler than the 5500.

With the help of Artic Silver 3, it has lowered my temps down by 3c idle and 6c under load. :thumb:
