De-lidded 3770k!!

Right, so i got to use the Liquid Ultra (on the chip) and Gelid GC-Extreme (heatsink) and also gave it abit more lapping with a sander :D Saves a lot of time!

Found the Liquid Ultra to be quite good to spread, was VERY gentle and used a tiny amount and brushed it around to cover the whole chip nicely, its just like melted solder.

The GC-Ectreme i found to be much harder to spread, initially i tried to use there spreader but found it so think it didn't touch it, so i wiped it off and just put a horizontal line and use the heat sink pressure to spread.

Got it all back together and left it to idle whilst i had a well deserved cig.

same condition as before, all fans at same RPM and all volts/multipliers left as they were, IBT set to custom 6500 RAM as before.

Old paste (CF3 on core and heat-sink) IBT:

New paste's (Liquid ultra on core and GC-Extreme on heatsink) IBT:

New Idle (Previous was about 22c)

So, like 6c drop at least on all cores! and massive drops on the last two cores that were running way hotter then i'd like, 14c on one and 15c on the other..just from paste and a 10 minute sander lap!

now, water cooling comes tomorrow but it looks like a barely need it :D

now to play with overclocking, the Vcore is high as the chip is voltage hungry and crashes (only) on BF3, whilst its stable in prime quite abit lower so *could be a driver issue.

I think I may use this stuff too now thank you. I like the way it won't spread around as much if the IHS moves slightly. Also, it's never going to need re applying is it?
 
What's the the liquid ultra? No I won't be reapplying it later when I get the water cooling in, just make sure I clean the gc-extreme off with the clamp on as to not disturb the chip. It's really very easy to apply, as long as you know it comes out quickly if to much pressure is applied and it kind of latches on to the tube lol. Brush makes it great to spread and a full stop size goes so far.

What's a safe vcore guys? My temps are great, will be even better on water but I'm worried that vcore will hold me up, do they matter so much as long as temps are good?
 
On air my max Vcore is limited by temperature. On water I think you are looking at up to 1.55V but I wouldn't for 24/7 myself. Can't seem to find the graph that Intel released showing the max voltages. On air my max Vcore is 1.39V because otherwise it hits over 90C. I'm happy at 1.25V 4.5GHz, considering I need to add so much to get it to 4.7GHz. On water I would say the same really. Personally I would try to keep temps under 65C and limit Vcore to do this. I am quite cautious though.

Ah right, well mine needs about 1.36 @4.5ghz to be stable in BF3, and those temps are still great. I've got the water cooling kit now so will be sorting that later. I'll probably see what I get at 1.4 but will want temps to remain at no more then 60 on load with the water.

I remembered that video yesterday and had a dream with me, didn't bother using it though as I've heard the lid can slip around..
 
I've tried it at 4.7GHz in BF3, temps were at about 66C during gaming instead of 50's. There was no performance increase so I just clocked back down again. After delidding I'm pretty sure I will just stay at 4.5GHz but will be tempted to clock to 4.7 because it helps my ram latency. :D
 
Yeah reading about it is putting me off buying it. People are saying the performance degrades over time, but not over a long length of time? I want to apply it and leave it there for at least a year. Might just stick with my GC Extreme.
 
No pics sorry, I think there is enough of them.

I was worried at first because the stanley blade is so FAT it bends the PCB.

What I did was just use the stanley blade to very carefully cut into the first corner. After that I tried to use it but it felt too risky, with £160 hanging in the balance I decided to try my original plan.

I took my Gelid TIM spreader, put it under the IHS corner that was cut. Oh, my, god. After that was in place, I had the IHS off in about 5 seconds. No word of a lie, the TIM spreaders cut through the sealant like it's butter. It's also very thin which is a bonus.

I was a bit gutted to see a tiny bit of copper showing through the pcb where I had cut the first corner, but lucky it was tiny and the system booted. Managed to use the TIM spreader handle to clean off the sealant too.

I really recommend using a TIM spreader or a thin piece of plastic.

This particular chip was sealed very well, it was hard to cut into the first corner it, that took the most time.

Going to load test it now will post images after. :D
 
My house feels a bit warmer today than when I tested for the Before picture, 12th to the 14th today.

Do you think it can cause damage if it shorts? I don't want to touch it, as far as I'm concerned it's a Gigabyte 3570K now.

Wazza: I agreee it is much harder than it look's. It's not as easy as people make it out to be. :p

Can you see that my motherboard PWM temps are lower today? Wonder if that has anything to do with the cpu temp.

I love it, my system now exhausts cool air under Prime 95. :D
 
yh if it shorts it can blow the transistors in the cpu ect,could have happened to your first cpu? i know you dont wanna mess but if you ever do then seal it with something,clear nail varnish or tape ect

looks good free 8-10c drop
 
Still cost me a 3570K though! Max temp during BF3 is 55C which isn't too bad. I might order some liquid metal and fix cover the cut, I don't think the cut is in contact with the IHS I'll have a look later on I think.

I think I cut through the tracks on the first one, might still be salvageable but I don't know what I'm doing. :p The dremel trick doesn't really work for me to clean off the sealant, fingernail was fine.
