Stock 775 fan vs. Hyper 212+ Passive

So currently, I have a Celeron E3300 overclocked at 3.5 ghz/1.4 volts with a Hyper 212+ without a fan, so it's running passive. The thing is, my case has really bad ventilation and the temps are hitting the high 60s under load (intel burn test). I was wondering if a stock cooler would be any better, or similar.
 
Why not add a slow-spinning fan on it? Scythe makes 500RPM and 800RPM SlipStreams, very quiet
 
The thing is, I need the fan for something else, so I was just wondering how the passive Hyper 212+ does against the stock 775 fan.
 
Generally, running a passive heatsink in an overclocked system with bad ventilation isn't advisable... I'd say the 212+ isn't doing too well, considering that the TJcase of E3300 is 74.1°C which your load temp is cutting pretty close to

Can you not purchase another fan? You can get a decent quality fan for $10ish or a cheaper one for less if you are broke.

As for how the stock cooler would compare to a passive cooler, I would expect it to do better since it has a fan actively moving the heat away from the heatsink.

TJcase? No such thing. There is Tcase, and TJunction. If he is measure 60C for Tjunction, under full load, then he doesn't have a temp problem, that's fine.

I would still personally probably install a fan, I like to keep things as cool as possible.
 
I kind of doubt the stock cooler would do any better. I use a stock cooler on a stock e7300 (similar generation as yours), and overclocked I can see the temps going through the roof.

Could you lower your OC a tad, and reduce the voltage? That will probably be good for 5-10C, and you might be able to still use it at 3.2 or something like that. Also, high 60s on a burn-in isn't horrible; your CPU should survive, but obviously if you can afford to give up a bit of the OC, you will have more margin for heat.
