First - - I would point out is yes Delta can give off a lot of noise but not so much in the 80mm size at low a rpm. <A HREF="http://www.deltaww.com/products/dcfans/pdf/AFB6060254_HIGH.pdf" target="_new">60mm at 7000rpm</A> can do it but not the <A HREF="http://www.deltaww.com/products/dcfans/pdf/ASB808025.pdf" target="_new">80mm at 2500-3500rpm</A>. Once the 80mm fans go past that, yes they can be loud.(My Opinion)

Both can be loud if your definition of loud is 30dBA which is comperable to a <A HREF="http://www.dataaire.com/heatexch/sound.html" target="_new">whispered conversation from three feet away</A>. Conversational speech is about 60dBA from three feet away. Choice of sound level is all up to the individual's comfort.

Second - - Which Globalwin HSF are you using? You might be able to change the fan on it without replacing the heatsink. You could go from a 60mm 7000rpm fan up to a 80mm or 92mm fan at a lower rpm and still have it move more CFM.

Third - - I will suggest that you use the <A HREF="http://www.swiftnets.com/mcx462.htm" target="_new">Swiftech MCX462-B</A> or the <A HREF="http://www.micforg.co.jp/c_pal8045e.html" target="_new">Alpha PAL8045T</A> if you do choose to get a new heatsink. Both models come without fans and I would encourage you to get an 92mm Delta to go with one if you choose to overclock.

(((See <A HREF="http://www.2cooltek.com/retro.html" target="_new">here</A> for instructions for mounting a larger fan to a HSF. This is a little different than the retrofitting a 80mm onto where a 60mm fan was but it will still work. The other thing you can do with both of these heatsinks, for a retrofit, is screw the grill into the existing holes and then screw the fan down to the grill.)))

Both of the heatsinks have better mounting mechanisms and both have very good reputations coupled with <A HREF="http://www.anandtech.com/cooling/showdoc.html?i=1532&p=2" target="_new">outstanding results</A>.

(Also see <A HREF="http://www.overclockers.com/articles373/" target="_new">here</A>, or see <A HREF="http://www.overclockers.com/articles347/" target="_new">here</A> for the articles from Overclockers.Com.))

(((Note: The Alpha was coupled with the <A HREF="http://www.overclockers.com/articles347/" target="_new">Oriental Motors'</A> Orix 80mm fan on the overall comparison. Orix are good for good CFM with low noise but a Delta 80mm will beat it for CFM.)))

If you don't want to mess around with fans get the Alpha PAL8045U or the Swiftech MCX462 because they come with 80mm Delta Electronics fans.

I hope that this helps.

I think the AX-7 is a good choice. Based on numerous reviews, it seems to perform on a par with the Alpha and the Swiftech HSFs. It attaches with a clip that uses all three prongs on each side of the socket, rather than just one. The Alpha and Swiftech models screw into the motherboard, so they're more difficult to mount. I guess it's up to personal preference which mounting mechanism to use. The AX-7 doesn't come with a fan, so you choose the kind you want when you buy it, either high or low rpm. The AX-7 is also a lot cheaper than the Alpha and Swiftech models, if that's a concern for you.

You can refit your existing heatsink with an 80mm fan if you choose to. If you look at your heatsink, the <A HREF="http://www.globalwinusa.com/products/fop32_1.html" target="_new">Globalwin FOP32-1</A>, you can see that you can use machine screws between the fins to attach a 80mm or 92mm grill. After the grill is attached you can screw the 80mm or 92mm fan to the grill.

If you look at the link I posted above for the Delta 80mm fan, you can see that the model ASB0812HH-F00 operates at 3250rpm, with 37.43CFM, and only produces 34dBA. That is 11CFM more and 2dBA less at a lower speed than your current fan. That <b><i>could</b></i> equate to a 2oC to 6oC temperature decrease. You could go to the <A HREF="http://www.deltaww.com/products/dcfans/pdf/AFB8080254.pdf" target="_new">Delta model AFB0812SH-F00</A> which is an 80mm fan that runs at 4000rpm, 46.62CFM, but gives off 40dBA. That would be 20CFM more for the price of an additional 4dBA's.

So the choices of combinations are limitless. All you have to do is determine what your cooling needs are, overclocking, etc., and what sound level you are looking for. The rest is just finding the fan and heatsink combination that you want. Like I said before, you can still use your existing heatsink if you like. If you are extreme in your overclocking than I would suggest one of the heatsinks I listed above. They screw into the motherboard which is a little more difficult to set up initially but will provide a very stable base for larger fans and the weight associated with them.

The <A HREF="http://www.micforg.co.jp/c_pal8045e.html" target="_new">Alpha PAL8045U</A> comes with the <A HREF="http://www.deltaww.com/products/dcfans/pdf/AFB8080254.pdf" target="_new">Delta AFB0812SH-F00</A> and the <A HREF="http://www.swiftnets.com/mcx462.htm" target="_new">Swiftech MCX462</A> uses the <A HREF="http://www.deltaww.com/products/dcfans/pdf/FFB808038.pdf " target="_new">Delta FFB0812SHE-F00</A> which is a dual fan design. (4900rpm, 68CFM, 48.5dBA…loud in my opinion. It also weighs 170grams.)

If you got the Alpha 8045T and the Delta FFB0812SHE-F00 it would be one extreme combination, not to mention a very heavy combination. That is why I suggested my choices for heatsinks. Your heatsink would not handle a fan of this size nor the torque produced by the weight of the fan on the chipset. The force of the airflow down onto the heatsink <b><i>might</b></i> detach it during operation since it only has one clip.

Like I have stated above, you could use your existing heatsink with a normal-sized fan (a light 60mm or 80mm) and a grill.(80mm) This would be the cheapest retrofit solution. If you are going to switch heatsinks and fans altogether the next cheapest would be to buy one with a fan included. The most expensive would be to buy a heatsink and a monster fan.
