[Video Added + Watercooling Results] Replacing the internal IHS TIM of an i7 3770K

post #1 of 298
Thread Starter 
I'm still debating whether or not I should be doing that. I started to think about doing it after reading this:

Intel Ivy Bridge CPU's Are Proven To Suffer From Poor TIM Choice

I don't care much about the warranty. I'm planing to replace the original TIM with MX-4.

Any thoughts guys? I haven't seen anyone doing it here so I guess I'm the first guinea pig smile.gif.


Do this at your own risk. You might permanently Damage your CPU if you're not careful. I will not be responsible for any possible damage you might cause to your chip.



Components that mattered:

Maximus IV Gene-Z
3770K
2 x 2 GB Mushkin 1600
H50 (1st Gen)
2 x 3300 RPM Delta
MX-4

Ambient through all tests (25.5 - 25.8C)
Stock Test: Everything on... stock - Memory running at 1333 9-9-9-24
OC Test: 4.2 GHz - 1.27 V - Memory running at 1600 6-8-6-24 (XMP)

Tests are finaly done and here are the results:

Decided to Run the chip under water with the IHS removed to see what temps I could get. I had to change some of the components for the watercooling test.

Asus Sabertooth Z77
8 GB Gskill 2400
Silverstone ST1200

XSPC Raystom
XSPC H2O 200 Pump/Res Combo
EK 240 (2 x 120) 45mm thick radiator
2 x Corsair 2600 RPM 120mm (Same as H100 fans)

Here are the results:

Stock Clocks (Under Water):


375


Improvement: 5.75 (Modified TIM) - 7.75 (Original)

OC Clocks (Under Water):


375


Improvement: 10.75 (Modified TIM) - 15.75 (Original)


----


Summery:

Use a higher quality TIM Intel, or better yet, just solder the damn thing.

I personally would LOVE to see this, and some temps before and after, but it's your chip, so your choice biggrin.gif

I would say most people would want you to, this being OCN and all tongue.gif

I don't think it'll help, only make temps worse. Gut feeling here.

Since the IHS isn't soldered, and there are no surface mount components on the CPU packaging (besides the die itself), it should be fairly easy to cut the IHS off.

I wouldn't expect to see a significant improvement, but if you are confident in your ability to use a razor, and really don't care about the warranty, you aren't likely to hurt anything.

Well damn it. I only have a Z68 motherboard available right now with no SB chip to update the bios with. It's a Maximus IV Gene-Z so I was hoping it had bios flashback which it doesn't.

I already have a Z77 board coming so I guess I have to wait till that one arrives.

I personally would not do it.

This is $300 you're talking about here. What you are trying to achieve is a higher overclock that can be sustained for a longer time period, am I correct? Then why not just save a potentially lost processor and replace it with a premium processor. $300? Get yourself a hexa-core, even if it's only for the e-peen boost! Heck, upgrade your video card if you want to see improvements immediately.

$300 can do a lot for your system. By cutting open your 3770K you can flush this money right down the toilet. You're not sponsered by Intel and you don't have a useless chip, so make it count. thumb.gif

What does getting a Hex core have to do with anything? That would mean I'd have to switch the motherboard too and that would cost a hell of a lot more.

Anyways, you don't need to be sponsered to test things out. There is a thermal dissipation problem with these chips. Like the link I provided in the first post, there seems to be a cure.

As for warranty, I don't really care as I've owned dozens of CPUs over the years and not one have ever gone wrong for me to replace.

If this ends up improving temperatures substantially you should make a guide biggrin.gif

hnh i thought the issue was heat leakage with the core itself and being inefficient. interested in seeing if this takes care to some of that/
