Acceptable VRM temps?

Wondering what is a "safe" upper limit temperature for motherboard VRMs? I have some component I'm messing with, 2600k and an Asus P8Z77-V LX. I have it stable at 4.3 GHz but 10 passes of IBT at "high" stress level sees the VRMs heat up to about 170F. This board only has 4-phase power and no cooling on the VRMs. 170 after less than 10 minutes of load seems too high, but this is based on nothing more than a gut feeling. Can anyone provide some enlightening insight?
 
Just keep an eye on your CPU multiplier under load.
ASUS / ASRock mobos pussy out and throttle the CPU if the VRMs exceed a certain temperature. Puzzled the hell out of me when attempting to OC a 2500K on a Z77 Pro4 awhile back (promptly returned that POS for a Biostar TZ77XE4).
 
Yeah, I think I may slap some heatsinks on them. I dropped it to 4.2 and lowered vcore accordingly and temps still got up to 190F during a blu-ray encode. I don't want them exploding off the PCB when I attempt 4.5+
 
190F/88C is complete in the realm of normal motherboard VRM temps and fine for full load. Nothing abnormal going on there.
 
Yeah, I understand that. I'm no longer worried about 190F, but I also want to push this thing even higher than 4.2GHz
