Here is the blow by blow concerning how to use the TIIM referenced by NickN in his FSX Bible on a Corsair Hydro Series H100i CPU Cooler, an Intel i4770k cpu and Coollaboratory Liquid Pro TIM (LMP).

 

First, you have to use the #8 Nylon Washer modification to the H100i backplate installation for the LMP to work flawlessly.  The reason for this is that when the LMP is applied it virtually  has NO thickness.  There are many references to a loose mount with the H100i with ASUS motherboards on the internet. Here is how to fix that:

 

Backplate (unmodified) properly installed (cutouts around screws) ...

 

Posts are too high ...

 

Washers installed on backplate ...

 

Washers in place ...

 

Posts flush with top of motherboard ...

 

Stand-offs installed ...

 

You can get these washers at Lowe's ... The Hillman Group 4-Count #8 x 3/8-in Nylon Standard (SAE) Flat Washers.

 

OK ... you start out with the contents of the package.  Notice underneath the two red lint-free nylon brushes is a pad ... as you can probably tell, this pad is kind of like a greenie-weenie.  It is abrasive.  You need it to prepare the surface of the CPU as well as the surface of the H100i. 

 

Notice the "scratchy" look of the stock CPU cooler that came with the i4770k?  That is what the top of the CPU and the bottom of the H100i should look like.  I used the stock cooler to practice the prep and application of the LPM ... they give you quite enough so practicing on the stock cooler is a real good idea.

 

Wet the pad with some 90+ proof isopropyl alcohol and scrub the top of the CPU until it looks like this.  In my case the lettering on top of the CPU is now only barely visible.

 

Mount the CPU in the LGA1150 socket on the motherboard and drape hand towels around the CPU just like a surgeon would do performing laparoscopic surgery.  Apply an indicated amount of LMP to the top of the CPU ... like this.  SPECIAL NOTE:  Do not dispense the LMP from the syringe like a doctor is giving a shot ... you could sploodge it out all of the electronics.  Pinch the syringe using forefinger and thumb using the left hand ... punch the plunger using forefinger and thumb with the right hand.  Gently and purposefully excrete a small, small amount on top of the CPU.

 

Using the provided lint-free nylon brush, work the LMP into the metal using small, slow and deliberate strokes ... until it is fully applied and it looks like this.

 

Now, moving on to the bottom of the H100i pump ... from the factory this comes with a nicely applied layer of TIM ... it is JUNK ... take it off.  To do this, use electrical tape to mask of the original dimensions of the TIM and begin wiping it off with a towel ... the process looks like this.

 

Then, use the scratchy prep pad and rough up the surface until it looks like this ... then, get any residue off using the alcohol pad provided with the LMP ... leaving the bottom of the H100i pump surgically clean. 

 

Apply a small amount of LMP ... like so.  Spread it around with the brush until it looks like this.  Note that I didn't cover the entirety of the pump like it was from the factory.  The reason for this is that the top of the CPU is already fully covered.  This is just to make sure there is enough TIM to get the job done.

 

Mount the H100i pump on the LGA1150 socket and you are all done.

 

Note, when you being to spread the LMP, it behaves like mercury at first.  It doesn't look like it is going to adhere to the metal ... keep working it ... using very slow, short strokes.  In time (like 7-8 minutes) you can stretch the small amount of liquid over an amazing area.  I swear this stuff is only a couple of molecules thick in places.

 

One note of warning.  Mounting the backplate using those nylon spacers makes it possible to over torque the H100i pump onto the CPU if you get too aggressive.  The thumb screws are large and using your hand you can put them on so tight that you can damage something if you go nuts.  Do NOT use a screwdriver, even though there is a screwdriver hole there you can use.

 

Using this TIM I quickly did a 4.4GH overclock on the i7-4770k (using ASUS AI Suite) and the temps averaged between 70C and 73C for four hours.  The temperature of the coolant in the H100i never reached over 34.5C (approx. if I remember correctly).  Some people have complained about the sound of those pumps.  My CPU is staying so cool that those pumps never really spin up so fast so as to be able to hear them.  This rig is virtually silent.  Also, I was going to order four Noctua NF-F12s and set up a push-pull situation on the H100i radiator to increase cooling efficiency and decrease sound.  There was no need.

 

Using the motherboard and the Corsair Dominator Platinum DDR3 2400 ... I am also running at the rated 2400 speed for the memory.  This was as easy as going into the UEFI BIOS and using the Corsair provided XMP profile for the memory ... timing is 10-12-12-31.

 

Enjoy!

Great post.

One caveat 90 proof alcohol is 45% Alcohol and 55% Water so a much better/effective cleaning liquid would be 100% Isopropanol (Isopropyl Alcohol) or 200 proof - not sure if you can buy that in the states.

Ah ... good catch ... my bad ... that was my intention.  The alcohol cleaning pad that comes in the packet is of that quality I'm sure.

 

Thanks.

I've played around with more overclocking options and it appears that 4.4GHz is as good as I can get without de-lidding the processor.

 

I'm betting that 4.4GHz will make FSX fly just fine and dandy.

 

I'm done!

 

I'm back to flying and out of system building for the foreseeable future.  Good luck to everyone!

Hi Charles,

 

You sure have done an excellent research! :biggrin:

 

At what frequency do ju run the Norht Bridge (CPU CACHE RATIO) on?

 

What is your  max VCORE and VCCSA when stress testing the 4.4GHz OC with OCCT Linpack (64Bits and AVX)?

 

My de-lidding lowered the temps with about 20 to 25C. Very impressive. But when starting the real OC:ing I discovered that my processor is really crappy :(

 

Got some excellent advice from Nick over at SimForums and finally managed to establish a stable OC at 4.5GHz and NB at 4.3GHz with RAM at 2400MHz (CL10 and 1T), which gives the score 37 770 with  3DMark06. Not that bad after all -_-

Yes always a tad cheaper :Money Eyes:

To be honest, I'm not sure I would use Liquid Pro "on top" of the IHS. It is electrically conductive, so I would want to minimise it's use.

 

I would reserve Liquid Pro for underneath the IHS when de-lidding. Installed there, as a characteristically thin layer it would be of benefit.

 

I don't believe Liquid Pro on top of the IHS, would generate temps much lower than the other top of the range TIM's to be honest.

 

 

 

Underneath the IHS: 10-30 degrees less.

 

On top of IHS: 2-3 degrees less at best.

Really curious what FSX performance you can reach with this system CT!

Here are some quick graphs from OCCT (about 3 minutes)

 

Voltage - CPU VCore

Voltage - +VCCSA

Temperature Core #0

Temperature Core #1

Temperature Core #2

As far as not using LMP on top of the IHS there is no cause for concern ... it is applied so thinly that it never "drips" ... the true benefit of using on top of the IHS vice using another great TIM like Arctic Silver I cannot attest to as I'm not going to use one, then test, then use another then test.

 

I hit 4.4GHz stable without delidding ... but I have a PTPP ... if this CPU ever dies due to the OC then when Intel replaces the CPU I'll delid it ... until then I'll stick with a 4.4GHz OC.

 

Remember, this is a crushing stress test ... when flying with FSX I might be running at 4.4GHz but the CPU will not be running at 100% over all cores ... temps should be significantly less than experienced above.  For example ... when typing this my Core Speed is between 800 and 1000 MHZ, Bus Speed 100, Core Voltage .272 and temps on all cores are below 30C.

 

I'm currently doing another stress test with AIDA64 ... temps are staying around 73C with 100% on all cores ... final results to be posted tonight at midnight ... for now ... this diagram shows everything to know to date.

 

Enjoy and keep the blue side up.

I'm now at 4.5GHz and 6 hours into an AIDA64 Stress FPU test.

 

Temps average around 70 to 75C ... Core #0 maxed at 94C, Core #1 maxed at 88C, Core #2 maxed at 84C, Core #3 maxed at 79C and Package maxed at 94C, coolant temperature for the H100i stays around 33.4C, H100i Pump 2160 rmp, H100i Fan 1 2021 rpm and H100i Fan 2 2027 rpm ... memory still at 1200MHz ... which is 2400.

 

This is good enough for me ... I guess I got a really good chip!

 

At this point it looks like a combination of the H100i, a good i4770k chip and Coollaboratory Liquid Pro TIM has resulted in a stable build ... at this point delidding for an addition 300 MHz would be crazy.

 

Thanks for all the help ... hope you all get equivalently good results.

Congrats on reaching the 4.5Ghz CT! Looking forward to see some experiences on your rig with a fully loaded FSX.

AIDA64 FPU stress test is good. But for checking temps You should run OCCT Linpack with 64Bits and AVX checked for at least 1h. You should also run OCCT CPU stress test for at leas 1h.

 

At what frequency do you run the CPU CACHE (North Bridge)?

Ah ... there ... you just had to go and burst my bubble didn't you <_< ... yea ... it didn't like 4.5 with OCCT ... back to 4.4 ... but that's not too bad I guess ... 4.4 is a good bit better than 3.5. 

 

I just had a scare though ... the machine wasn't keeping time ... it'd keep time for a couple of hours and then just stop ... come to find out that the motherboard shipped with a bad CMOS battery.  Replacing that battery seemed to fix the problem ... won't know until tomorrow sometime.  If I have to pull that motherboard out because of a bad BIOS chipset ... I'm just going to go ahead and delid while everything is apart.

 

How do I tell what the North Bridge frequency is?

NB frequency is displayed on the Memory tab in CPU-Z. The BIOS settings are MIN CPU CACHE and MAX CPU CACHE.

 

My 4770K turned out to be one of the real crappy ones. Very high temps at 4.2GHz with OCCT Linpack. De-lidding lowered temps 20 - 25C, but I needed high VCORE and VCCSA to be stable at 4.5Ghz with NB at 4.3GHz :vava:

 

Nick N helped me out on how to get my overclock at optimal settings within voltage limits :good:

Ah ... there it is ... NB Frequency is 3906.7 MHz
