    Plus, you can increase the pressure further by putting something inside where the knob screws down.

    I am very anxiously awaiting a thread with lapped vs not-lapped... oh and possible delid?

    My old U12P is as flat as any heatsink I've ever seen, confirmed with a proper straight edge. If Noctua is anything like Thermalright, they won't have changed their base plate in the last couple of years...

    The Noctua coolers are actually super easy to mod for this, just put a shim exactly the thickness of the IHS directly next to the springs on the screws and you have exactly the same mounting pressure as before with the IHS. Much better than using the Venomous X's adjustable mounting pressure since there you can't be sure that you keep the pressure constant between IHS/No IHS (not that too much pressure would make much of a difference, never did in my tests with a TRUE and shims).

    So I still have my trusty Storm Rev.2 from the AMD64 days. I'm wondering how a 3770K would do delidded and WCed for 24/7...

    Currently running prime95 on blend at stock 3770k voltage/speeds (looks like 1.112v under load @ 3.9ghz) with my venomous-x. Currently the maximum temperature is hitting about 57C (57/55/52/52 for all 4)

    its not about cooling performance, its about comparison between lapped vs no lapped, possible delid vs lid. venomous has pressure adjust to compensate for lid being gone.

    It's possible I'll test a delidded CPU. I have ~$210 in my "extra Ivy CPU" fund, so I still need about $110 or so before I can do that.

    Overall max temps don't matter, it's the temp differences between the different setups: not lapped IHS, lapped IHS, no HIS, TIM change + lapped IHS, etc. So, whether the cooler is the best for the chip or not doesn't matter because we'll be looking at temp differences, not overall max temps.

    Saw this a while back...

    According to a post over at Overclockers.com, the first reason is only partly true as although the power density is indeed greater it can't explain a difference of up to 20C when overclocked Ivy Bridge and Sandy Bridge are compared. Although, there is also a minor possibility that second reason has something to do with it as Ivy Bridge certainly has a lower overclocking potential, but mostly due to heat, as some reviewers were even scared to push it beyond 4.5GHz.

    Do you have any comments to this test? that place the heat sink directly on the die and find that temperatures are similar. The weakness in their argument is that they equate their die -> paste -> cooler assembly with a die -> solder -> IHS -> paste -> cooler assembly. They don't test Ivy Bridge with a soldered IHS.

    you can't test Ivy Bridge with a soldered IHS as IB isn't (as far as we know) soldered with any of their chips and Intel uses a special kind of solder that melts at a lower temperature than most other solders (and I'm sure is a special blend)

    "This is as designed and meets quality and reliability expectations for parts operating under specified conditions," Intel explained

    Ugh. This sounds suspiciously like "we're not trying anymore because we don't have to".

    This, to me, is the bad side of AMD backing away from the high end CPU space. I understand Intel's point completely from a cost standpoint, but not on a -K SKU CPU. Charge the extra $50 for a soldered -K CPU and give us an unencumbered enthusiast part, because an unlocked multi and a -K in the name does not an enthusiast part make.

    They're not backing away, they just can't compete. This is why they're going down the APU path. Convince coders to develop to use GCN and Intel won't keep up.

    They can't beat Intel at their own game, so try change the game. It's the only approach in which they have a chance of actually beating Intel. They don't have the $ to try anything else.

    just hopefully putting all their eggs in this one basket doesn't fail.
