Running a cpu with a heatsink but no attached fan......

[spoony77]

Hi people
So I just moved my htpc into a mini itx case the sugo sg13 and have come up against an issue where my cpu with its heatsink on only has 15mm clearance to the psu. (won't fit with the standard fan on)
I have pointed the fan of the psu down so It exhausts/sucks air away from the heatsink.
Will this setup be OK for a htpc with some light gaming?
I really don't want to have to buy an AIO cooler but I have seen some low profile 15mm fans but I'd have to somehow glue/wedge it to the heatsink as there is not enough room in this tiny case for the required 120mm fan that fits this heatsink.
What do you guys think?
Kind regards

Thanks for the replies guys.
It's an i5 2500k but it won't be overclocked and am happy to undervolt it.
I wondered whether or not I could somehow get the cpu fan to blow rather than suck but then I thought that would be pushing warm air over the fins of the heatsink rather than cool air.
I have a 120mm fan at the front but it's not the mesh version of the case so I'm not sure how effective that will be.
Im gonna switch it on and see what the temps are saying then update this post.....

So I did some tests and it's idling around mid 40s using Intel speedstep and going upto mid 60s under light load so not too bad.
I've set coretemp to turn off the system if it hits 75c so hopefully that should be OK whilst it's winter and I will re-assess in the summer.
Loving this little case though not sure I'll ever buy full size atx again!

The motherboard seems farely basic it's the P8H77-i by Asus and I can't see any power limits in the bios or even temperature limits hence why I'm using coretemp from within windows for the safety cut off
