Old Lian-Li PC7 vs New PC7

Prophet · 19 Sep 2007 at 10:47

I've got an older PC7 (2X80mm front/1X80mm rear/No top fan) that houses my current rig. I'm thinking of upgrading to a C2D with an 8800GTS. Do the newer 120mm PC7's privide anymore cooling compared to the 80mm versions?

I'm not 100% sure I'll go with a Lian-Li but would like to know the above in case I do.

Cheers.

120mm fans will aways provide better cooling than the 80mm fans....

1X120 is better than 2X80?

Not saying its not just need a little more convincing than that

Could always mod your existing one, take about an hour or two.

This was my 6002 (even cheaper version of PC-7) they are identical to the 80mm version of the PC-7 internally.

Rear is a very tight fit against the I/O frame, almost don't need to fix it in place. The notches were to fit a wire guard internally but never did.

Front needed careful alignment to avoid the existing holes and cut-outs, and low enough to avoid the 3.5"frame.
Use some spacer blocks (~20mm piece of tubing) and the front USB ports are still usable.
I notched the USB bracket fixing holes to use the same screws to mount the fan.
The filter is still usable and covers most of the fan area.

Nice mod there. Has it made a big difference?

it should do, as already posted 120mm fans are better than 2 80's

Can't compare as I never even used it with the 80mm fans and I mounted a rad to the front and watercooled it.

This was how it ended up (socket A - going back a while!)

Generally though it's all dependant the fans used, at the same CFM the 120mm will be very much quieter.
