I see my tests were received and why my temps were not affected much by the TIM.
test 1 and test 2. Thanks ICD7.

 

[Assimilator1]

Are mine in there?

I loaded up Asus PC Probe II to do my initial check of temps with the current install using Artic Silver 5. Load temp was 63 degrees and idle temp was 39 degrees.

Ends up the stock heat sink was not anchored completely. I hate push pin HSFs.

Hardware
[*]mobo: Asus P5L-VM 1394
[*]CPU: Intel E2140, stock
[*]RAM: 4gb GSKILL 667 MHz
[*]HSF: stock Intel cooler

Stock cooler with AS5
[*]idle temp: 21c
[*]load temp: 31c

Stock cooler with ICD 7
[*]idle temp: 21c
[*]load temp: 32c

When removing the heat sink to install a new TI-128, I noticed the spread wasn't much at all from the pressure of the stock cooler. I'll benchmark temps with the new cooler next weekend (hopefully) and see what happens with it. Also I'll see if I can OC it--especially considering I know now what temps it can handle.

Also, I didn't seem to have any problems at all with applying it. It wasn't nearly as bad as using Ceramique.

Tests were not entirely what I expected. I thought I was pretty good at reading grease contact patterns as I look at more than most. Intel stock coolers were/ have been one of my problem areas. See how it looks after I process the data.

Thanks for helping out and taking the time to test

 

[Assimilator1]

You awaiting on anymore film results?

I definitely won't ever be using them again, except for very temporary cases.

On the whole the stock sinks did not do so well around 5 or 6 tested were either a degree higher or 1 C lower with the exception of Martijn over at xtreme with a bolt through mount got around 4 and 5 C.

One guy used push pins and a bolt through and had great contact with 62 lbs force and got -1C on both tests...

I have been ruminating on the design- smaller footprint increases the force and takes the sink off of the non bendable edges. The design intent though seems to be consistent but reliably mediocre.

Where on say a Zalman the difference or swing in temps could be 7 or 8C . The stock range is much tighter +1 or 2 or minus 1 or 2 C pretty stable and forgiving but not real exciting.

Yours are posted 14 a & b. You have one of the higher pressures on the center with a good improvement. Some have comparable print contact patterns and did well also and some did not . It will take me a couple of days to sort it all out.

 

[Assimilator1]

Thanks
My pressures are rather high for my Ult 90 in the middle!, I was right not to put 2 washers under each screw then!

I wonder what Insidious got? (couldn't find the pics).

 

[Insidious]

Mine are #23

[Assimilator1]

Where do you see these numbers?

 

[ICD7]

Insidious -Series of articles on the results will be posted over the next couple of days on overclockers.com your 23 series of progressive lapping is compared so you are soon to be famous as a lapper extraordinaire

Hey that's pretty cool... thanks!

(just tell me I'm not going to be the bad example... )

Insidious you are a good example for the rest of us.

I was surprised in general at the results. High force seem to dominate with contact. The IHS's were all over the place in impressions, concave, concave with a hump or island in the middle 2 high edges with 2 low one etc.

In most cases I myself probably would have lapped the sink and assumed the IHS from intel was good enough.

If they had low contact and low pressure they were the ones that registered a higher thermal result.

on the whole it is kind a confirmation of you guys already know, good contact and high pressure solves alot of thermal problems.

It is kind of a subtle thing. How much force are you applying? How good is your contact? There are few observational tools available to the average user other than a general impression of the temps not feeling quite right on a new install.

 

[ICD7]

We have been organizing results from our pressure testing into a series of articles for a final report of results the first of which has been posted HERE for those that are are interested

Informal survey

How many of you disabled the Intel fan PWM for your test? I am a total **** on the subject so any input would be helpful

I am always looking for reasons why people might not see a thermal result with the IC diamond paste with good progress on the contact side of it, but with some outliers outstanding I have been noodling over, this was a long shot idea I had and I am not sure if it has any merit or not

The temp of the diode controls the fan speed, so if the cpu is cooler the fan speed would slow down in response, in effect allowing the cpu temp to catch up temp wise to a baseline sink comparison. Make sense? I don't know if that actually is what happens But I would assume it would introduce some variability in the results

And how would resetting or calibrating the temps under hardware monitor vs real temp and others affect the PWM duty cycle?

I am guessing from the Intel docs ranges are stepped either 5 or 10C increments or is there more flexibility like 2 or 3 C?.

I suppose that you would only see that if you happened to be straddling ranges on the before and after result?

 

[Assimilator1]

I'm pretty sure I have PWM off.

And yea if PWM is on & a better HS paste improves cooling then the fan speed would be slowed down to maintain the same temperature range (if ambient's the same) AFAIK.

Congrats on about to become famous
Which 23 are your pics? or is it all of them?

Many thanks to those on the forum that took the time and effort to test. much appreciated

 

[Assimilator1]

Thanks .

 

[Fullmetal Chocobo]

Excellent. I'm definitely ordering bolt-thru mounts for any HSFs that have push-pins. My two examples in the "bad pressure" section are proof enough for me. I also think it's about time to redo the TIM on my primary rig.
