HDD cooling w. intake fan?

[Showlow]

I'm currently building a computer from scratch and the case has 2 intake fans and 2 exhaust fans. It is designed so I have the option of mounting one of the intake fans on one of the HDD cages, or simply leave this cage (with fan) empty of HDDs.
I am debating which way to go...
1st option: The 2 HDDs get a nice breeze from the fan but this increases the temperature of the air blown in the direction of the motherboard.
2nd option: No cooling of the HDDs, which probably will lower the case temp but increase HDD-temp. Still probably within operating spec though.

1st option is not optimale since I intend to overclock the system (case temp), but on the other hand the HDDs I got (IBM 120GXP) apparently tend to run pretty hot. (see http://www.storagereview.com for update on these drives...)

What's your take on my best bet with my current equipment and 4 case fans?

As long as you have adequate exhaust in the rear of your case, I really don't see a problem with cooling your drives. Consider this;
those IBM drives will last a lot longer with appropriate cooling, and you'll more likely replace the CPU before the drives. The amount of heat, IMO, is not enough to seriously hamper your OCing efforts. Also, if you don't cool the drives, that heat stays still in your case and eventually builds up.

is there a way i can mount a heatsink of some sort to the HDD? or a waterblock? =P
