Try it but you should usually get an aftermarket fan for overclocking. Just monitor the temps and make sure they are not too high, and know what you're doing. Something cheap like the Cooler Master Hyper 212 +/Evo is a great budget choice for overclocking or keeping temps down(which is what I got mine for).
If you are going to overclock I would always advise that you look for a 3rd party HSF (heatsink/fan). At least with the Intel® stock HSF we design them for the performance at stock speeds and performance. So when you are overclocking you are going to run into temperatures higher than what we designed the HSF to deal with.
