I use Velcro tape on my odd assortment of fans, water cooling creates a few dead spots for air circulation as you water coolers all know.

how are you going to mount it? i have a few of these lying in my spare fans draw but theyre designed to go in a pci slot, admittedly it would provide even airflow for all but how are you going to mount it please? id like to know so i can have a go!

Thanks,

Craig

With not enough anchor points for "custom" fans there are still ways to put that fan where you want it. Caveat,
I haven't mounted powerful 80 mm's like this, just weeny 20-30 cfm fans. Suspend the fans where you want them using tie-wraps also known as cable ties, or even dental floss or other no foolin' strong string. As long as the fan can't move more than a centimeter or so, this method works OK. If you can suspend a bridge, why not suspend a fan?

of course, however, Im really not too sure how much of a difference the heatsinks really make if any. I mean, if you look at the proper way to heatsink a mosfet then you must first either free the mosfet and mount to the ground plate in the back or...better yet...they should have done that in the first place. If you look at everything we do to our boards in order to make pushing them harder a little safer youll soon notice that a fair amount of time and money gets spent. What amazes me is that someone doesnt make boards based on popular boards with modifications like better capacitors, properly presunk fets, and even a cdbay consisting of vr's and tiny lcd displays for control of the vdimm,vdd,vbt and vcore. Obviously they make a fair amount of money off those of us that break a ic pin now and again....but geez, its just a matter of time.
Some of the fets I deal with at work are seated in a heatsink that flowers outward to dissapate heat. Surely thats not an expensive thing to add to a board.


edit: WHOAA WAIT!!!! Im not saying you should attempt to lift your mosfets....dont even try it cause they have some hefty solder on there...takes about 850 degrees to even begin to melt. By that time the heat has traveled to the caps and possibly warmed the pcb to the point of conductivity....just saying they should have done it in the first place!

The reason comapnies dont do this is cost. Its costs to do this. THis is why we still have passive cooling on NBs. Id doesnt take much to put a heatsink on mosfets, what would be good is if they had speciaalist sized heatsinks for each board with holes like around chipsets to make it easier to mount.

The possibilty of an overclocking only board, well not only but overclcoknig specialist would allow manufacturers to chnage a premium. I.e. youd be paying for better otpinos in BIOS and also betetr capaciators. Also, as a side note the 8RDA should need moseft coolkning as thermal pics have showed it gets very hot.

the hotglue works well. i have an 80mm glued to the side of my case, hasnt caused any problems or fallen off. just be careful if you're dicking around inside the case or moving it. the stuff breaks pretty easily.

8rda+...

I put the sinks on anyway however the real heat is at the base where the ground plate is. I was curious on why the color of the pcb is changing color so I just pulled out one of my old 8rda+'s and pulled off one of the fets just to see what protection they put on the board.....not much. As you can see in the pic its just a small square of fiberglass glued to the board. These boards may claim to be capible of 2v-2.3v but really they are not....at least not for long periods of time. I have only done about 10 hours on my 8rga at over 2v and then I was limiting myself to 2.1v. If toasty coils and fried pcb is there way of handling 2v then I hate to see what marketing scams they come up with next....just ticks me off.
I started with the 8rda+...just as I had gotten the nerve to volt mod everything the 8rga gets announced as being capible of more through the bios...hearing that many people killed their 8rda+ while running on volt mods I figured I would save myself the headache and grab an 8rga.....now all Ive done is tap my wallet further and postpone my headache.
