3770k IHS Removals - CPU temp dropped from 79C to 71C

[Zeus]

dr_dx, unless you are using a chiller or it's freezing in your room your temperatures are off. I don't mean to take anything away from you and yes, i am jealous at your cpu but 13ºC idle on the lowest core is impossible with normal water or aircooling.

Still some good overclocking on your part and a truely awesome cpu!

[dr_dx]

Ultra Pro?
Do you mean Coollaboratory Liquid Ultra? Coollaboratory Liquid Pro? Something else?

Yes, Liquid Pro. Thanks for pointing that out - I edited my post.

Just top-chopped mine. I can't believe how easy it was. Literally 3 minutes and it was off. I used one of those razor blades that are used in hobby knifes to scrape of paint or something.

When i lay the heatspreader on top of the cpu it is "floating" on the die, the edges of the heatspreader are not touching the PCB so no need for lapping the edges of the spreader.

I'm gonna put Liquid Ultra in between and glue the spreader back on.

2 year old $100 homemade chiller - 60F~75F

I will update chiller thread with my current setup.

Ambient in my room is 27C.

Just FYI - Liquid Pro has at least 2x the conductivity of Liquid Ultra - see post #298

[Zeus]

Ok Doctor, thanks for clearing that up.

I already have the Ultra and it was the only Liquid Metal i could find locally. Pretty sure it will still be better than AS5 and co, right?

[dr_dx]

Absolutely!

[Zeus]

Just finished the assembly. Added a small bead of rubbery black adhesive that's rated up to 90ºC onto the edge of the spreader, carefully placed it back on top and removed the excessive glue with a couple of q-tips.

Put the clamp on and now we wait for 24 hours.

.

If you use 4 threads in LinX, you will get higher temperatures.

Just got my liquid pro...and tomorrow is a holiday for me...

Any last minute tips?

[Zeus]

I found out the glue had cured so i'd put the cpu back in place and tested. I am oficially shocked!

See for yourself:


Before:



After:



If you think this is impressive i have to add that ambient today is 5ºC higher than when i tested with the stock tim. So basically i gained over 20ºC on the hottest core!

I used Coolabratory Liquid Ultra between the IHS and die and Prolimatech PK-1 between the IHS and my waterblock.

Now i have to find out if it gained me any overclocking headroom but first i'm gonna enjoy my temps.

wow what a neat job what glue u used mate ?

[Zeus]

Thanks mate. It's called Rubson FT101. Not sure if it's available outside of Europe though.

Delided!!!!!!!!



Before temps at 4.5 Ghz 1.20V, max temp after two rounds - 72



After temps at 4.5 Ghz 1.20V, max temp after 2 rounds - 60



Awesome temp drop on 3 out of 4 cores, but I think maybe a clean up and re mounting is required. Used Collaboratory Liquid Pro.

I should have used Linx, but in my hurry I ran IBT.

Hy Guys
Here is my rig after 11 minutes of Linx with Coolllabolatory Ultra on both die and IHS.
Yes you're not beeing wrong, my CPU is a crap: 1.48 for 4.8 GHz but who gives a dame I enjoy those low temps :p
I find LinX to warm the CPU more then Prime blend within first minutes test.

[owikh84]

5Ghz @ 1.288v
IMHO, Liquid Pro is definitely the way to go; used on all 4 surfaces (all surfaces need to be "wetted"). Use a very small drop on die and underside of IHS - a little goes a long ways. BTW, I didn't have to lap the IHS, after cleanup, it was resting on the die. Highly recommend using a single sided safety razor. Very thin blade, will cause the least amount of PCB distortion. Just rock it back and forth and you can be done in less than 5 minutes.

Holy jesus 3770K, amazing temp on 5GHz!!

[OldChap]

From observations only I would say that the cooler the cpu runs, be that through chilling, new tim or just plain old ambients, the lower the voltage needed for a given overclock.

As the weather got warmer here my MOAF cooled 3770K has needed more voltage. I need winter to come around to see if this is really true or if I am seeing degredation.

Hi, finally arrived liquid ultra and put it to die and ihs, the temps went down around 10 degrees more from as5+as5. Anyway this chip is quite crappy and will stick it to 4.7 with 1.4v ish.

Im thinking to use it with gtx480 and accelero twin turbo 2, do you think will have some problem? Not sure the ihs and anchorage materials. Thanks in advance and soz for offtopic.

I wonder if Liquid Ultra is just about as good of an option for IB die as Liquid Pro is.
The reason being that its structure resembles paste and, thus, is more likely to work better in cases with uneven surfaces and poor contact, while Liquid Pro makes a very thin layer.
Or am I wrong in this assumption?

As long as it does not come in contact with aluminum it will be fine. Liquid Pro worked very well back when I used it on 8800 Ultra, and Liquid Ultra generally seems much safer.

[MaynardX]

Everyone who struggles whether to use CL Ultra, look at the screenshot below.
I mean 1.505 Vcore shall I name quite nasty for a liquid cooling (it tops a notch during full load 1.512). Sorry I don't have a screenshot for this, but with IC Diamond on both IHS and die it was impossible to reach even 1.495 due to 98C.
Right now I have 80C on the hottest core with 1.505 Vcore, so CL Ultra is worth the try.
At the moment I don't have time for this, but in a while I will try lapping the inner side of IHS. The reason for this is this "stain" of residue (I guess everyone observe on their samples after the IHS removal) which might affect the overall thermal conductivity.
Last comment concerning temp reports. I think one should mention his/her ambient temp during the tests, as IMHO this temp is also crucial for CPUs thermal measurement.
So below your post, give us your ambient temp.

My ambient for the measurement below was 22C.

Yes, thats the problem, not sure the materials involved, would say copper nickeled for ihs but not sure about the accelero anchorage. Really doesnt seem Al but could be an alloy and could have some Al. I sent mail to arctic cooling and they told me I should use mx4 or my 480 ihs could be damaged

wow what a neat job what glue u used mate ?

I suggest of three choice for you, all are same compound with intel used

Permatex 81158 Black Silicone Adhesive <<< best one (Recommended )


Shin Etsu KE-45W (they have five color > Transparent, White, black, Gray, red


3M 08011

Got new answer from arctic cooling and no alluminium in both base and anchorage.

Do you know if 480 ihs is nickeled copper?

I understand. Other than the TIM, I was trying to create an identical test environment. Since the before was run with HT on, I ran the after with HT on.

Any last minute tips?

Make sure and "wet" both/all surfaces.
