My guess would be the IGP kills the overclocking potential. Even if it has separate clock and voltage control, the fact that it's on the same package probably screws around with stability in one form or another. Look at i5 overclocking with the onchip PCIe.
I am sort of thinking the same thing. s1156 i5/i7 is a bit hamstrung by the on-die PCI-e controller, though problems with it can be partially overcome by just raising vcore as indicated in Anandtech's i5/i7 review (basically, increasing blck = increasing PCI-e controller clock speed, so to stabilize it, add voltage to the chip where it resides, which on an i5 and s1156 i7 entails raising vcore).
On i3 it almost looks like you'll have to increase voltage to the die with the imc, PCI-e controller and IGP in order to offset PCI-e controller overclocks. The IGP will hopefully drop into a power-saving state and/or be shut off entirely whenever a vid card is used, something of which I'm sure Intel is capable.
I was thinking of using a Corsair H50 mini water cooler for these two reasons.
1. It would fit nicely in the Sugo Sg05 and the radiator could be put directly behind the only fan (120mm front intake fan bringing cool air in from the outside)
2. I think a water block might do a better job at cooling the hot spot than a symmetrical heat pipe Tower cooler.
But honestly Turbo mode on Core i5 750 sounds pretty good (after reading post #233).
That cooler looks interesting. I wish there were more benches to show where it performed versus the Megahalems, TRUE, and other top-tier HSFs. I've heard the H50 is nearly silent so if that's a problem, it's worth a look. Only problem I've heard about it is that it sometimes offers up high idle temps and it often takes awhile to deal with load swings/spikes.
