Upgrading processors - Do I need a better cpu cooler?

I presently have a Dell Optiplex 745 that has a Core 2 Duo E6400 CPU that runs at 2.13 Ghz. I just recently purchased a E6700 2.66 Ghz processer. They are both LGA775 chips.

The PC came with a large heatsink connected to a fan that blows outwards to draw heat from the heatsink. I am concerned about this new CPU might run considerably hotter than the old chip. Because Dell likes to use proprietary components I don't seem to have much of an option as far as upgrading to a bigger heatsink. (heatsink brackets are attached to the motherboard)

Is there any option that I have now? I have thought about purchasing a few larger fans and putting them inside the case to optimize airflow but my main concern is the possibility of the CPU overheating. I have also considered liquid cooling but that get's expensive and I'm not sure about compatibility with Dell cases.

Any suggestions or feedback?

They both have a TDP of 65watts so the same cooler is fine.

thanks for the tips all, i will definitely blow out all the dust/debris inside the mini-tower as well as cleaning the heatsink itself.

As for the thermal compound, I brought some $5 stuff at the local Microcenter. Not sure what brand it was but i'll check again.

Decided to play it safe and purchased the Arctic Silver 5 paste, I heard its probably the best paste you can use......

Thanks again !

No. It is no longer the best. The best out now would be Shin Etsu, IC Diamond, and MX3/MX4.

Anyways, not to be a d1ck but that upgrade was some what pointless. You really won't benefit much from that extra speed in most cases. How much did you pay for that CPU?

^ Yes. It is still a good choice, but imo, it is now over prices (in terms of price vs performance).

Shadow: Actually it wasn't really an upgrade, I brought the case/motherboard from a guy for really cheap but it didn't have a CPU or RAM, so I did some research and found the E6700 2.6Ghz processor to be the fastest processor that will work with the mobo and chipset (it was a pain in the ass cuz Dell uses these Foxconn boards that are not documented on Foxconn's site.

Anyway, I paid $80 for the CPU on Fleabay (yea it sucks that I paid so much but thats what fits the board and Intel no longer makes those chips else I would have brought something better.
