Koolance and Enermax power supplies

I just got an Koolance PC2-C and enermax 2 fan pwr supply, and I'm trying to decide if I should mount it upside down as the koolance site suggests or cut a whole in the plastic divider so the fan can inside fan on the pwr supply can do it's job properly?
Anyone have any suggestions or simialr experiences to share?
thanx

I have the same case with an enermax power supply also . I mounted it upside down so the psu's fan would help the third fan of the case to suck the hot air out.

Works great, temps are awesome

Thanx for the info, have you added any xtra fans to the lower half of the case as well?

i have my fan facing up for the same reason, the fan blowing out the top helps get rid of the heat from the PSP

the divider was put there to keep out the heat generated by the PSP

I havent added any fans yet but I plan to do so when I have the time, the airflow will be a great help for the vid card and chipset cooling.
