So I recently switched over to a full custom water loop, and since I'm using the EK Supremacy block, I thought it would be a shame to not de-lid my 3770k and run their Precise-Mount kit for Naked Ivy's.

Everything went about as smooth as it could, but my temps dont feel right.

Core 1 seems to be where I should be at, sitting around 23c under idle (@ 4.6Ghz 1.29v)
Core 2 (24C) and Core 3(25-26C) run a little hotter
Core 4 however is a hot tamale, sitting at 33-34c under idle conditions. At load this core can hit 75C!

Core 1 never goes above 53c under load, and core 2+3 stay around 65c under load.

I guess my question is how can I get the rest of the cores down to the same temp as Core 1, most people report ~20c drop in temps when running a similar setup, and my Core 1 shows that can happen.

(Testing done with PK-1 paste)

I should also mention that I did a mount test, and the paste did cover the die in a thin layer and seems to be making good contact.

By me its always core1 that's the hottest, core2 & core3 (2-3C lower), core4 the coldest (10C difference).
Not delided.

Idle temps are around the same across all cores (2-3C difference)..

Poor TIM that Intel give us !

Before delid my core#2 is the hottest core ~10C more than other cores.

After delid every cores is equal except core#0 cooler than other cores ~5-10C.

From what I've read its not poor TIM fault, but rather that extra gap between cpu pcb and glued IHS, if they used a little less glue 0.01?mm all would be ok.

Well, I figured I would post my solution for this.

I decided to replace the PK-1 with some Coolabratory Liquid Pro. I was a skeptic for the price, but it seems for a bare die mount its the way to go.

Core 4 on my last bench hit 80c before I tore the PC down, now it doesn't go above 61C. (So -19C from PK-1)

Core 2 + 3 are 57c + 59c (-8C & -6C From PK-1)

Core 1 (Frosty as Always) 49c (-4C From PK-1)

All in all, temps dropped across the board which I am happy with. It took a minute to learn how to spread the stuff, and I'm interested to see how it looks in a years time.

it is the tim that intel use, the heat from the bare dye just bakes normal tim and liquid metal is the only way to go :)
