putting an 80mm fan on a 60mm heatsink...

[B00mer00]

I heard somehwere that instead of buying an adapter you could just turn the fan 45 degrees and screw it on with 2 screws. my question is if this will hinder performance in anyway, and if i should just stop being cheap and buy the damn adapter.

You could do that with an SK6 because the fans are hold on by two clips. You just turn the 80mm fan 45-degrees and clip over the corners of the fan. That's the only heatsink I've seen that you can do that with. Most of the other ones screw the fan into the fins on the heatsink and with an 80mm fan, your screwholes won't line up at all.

yeah, just buy the adapter... hehe

Don't waste your money on an adapter, get a GC68 from SVC that accepts an 80mm fan without an adapter and it works great.

or you could get a Zalmon Copper Flower and put a 120mm fan on it

 

[B00mer00]

damn I have a golden gate 40 so it looks like ill have to get the adapter thanks for all the input anyway.

 

[B00mer00]

ok i got one more question. is there an adapter to fit a 120/92MM fan on a 60mm heatsink? if there is where can i get one?

 

[grrl]

What is your reason for changing the fan? I hope not to get better cooling because with the back pressure created by the adapter you will get LESS cooling. I don't know how much the adapter costs, but for probably a little more money you can do what others have suggested and buy a HS that directly accepts an 80mm fan.

No need for an adapter.

Get an 80mm Fan Grill.

1. Measure the width (thickness) of the stock 60mm fan. Obtain enough washers that measure the same thickness of the fan. You will use these as spacers, or make a shroud out of cardboard and save spacers for later, to attach to all four sides for optimum airflow. Alternatively: you can substitute some other kind of spacer. If, for example, you have a broken 60mm fan, you can cut out the fan and use the carcass as your spacer + shroud to channel air.


2. First, put the screws that came with the heatsink through the 80mm grill, between the outer and 2nd farthest rings (or wherever it fits). Then then add washers or use carcass of an old 60mm fan. Then put that assembly into the heatsink. Screw it down onto the heatsink. If you used washers, add your shroud walls now.

Here's what you should have in this order:

Screw.
Grill.
Washers or Other Spacer and shroud.
Heatsink.




3. Screw your 80mm fan onto the opposite side of the 80mm grill. So if you're working on a table, you'll have the reverse of the above list, with the surface that'll touch the CPU facing you. Put this on top of the 80mm fan.

4. Screw or snap the whole assembly onto your CPU.

5. Enjoy.

I hope this is clear.

What's back pressure?

I have an 80mm on my PAL6035 using an adapter. Yes, I had to rig it in there useing cardboard because the screws they gave me weren't long enough but it seems to work fine. Now if I have it sucking air off the heatsink how is it going to create back presure?

 

[grrl]

Back pressure is caused by an restriction in the airflow. If you are sucking the air through the heatsink there will still be a drop in air flow because the unit is set up for a 60mm fan (i.e. at least one dimesion on the HS is 60mm I assume). The drop may not be as great as when you are blowing air through the HS, but I'm not convinced you will get that much more cooling.

 

[SithSolo1]

If you are sucking the air through, the only thing restricting air is the heat sink. Using a 60mm or an adpter doesn't matter since the air is flowing trough the same size hole to begin with. Now if you are blowing I can see how it would cause back pressure. Blowing with a 60mm, it travels through a 60mm hole the enitre time but with an adpter its going from 80 to 60 and thats were your pressure and I just realized I'm fighting over an issue that doesn't even pertain to me and I owe you an apoligy. Sorry, hehe.

well at least if the fans going to "pulling" air off the heat sink you should have a shoud over aprox the top 2\3's to help direct the air.
have fun
