BUMP - dear mods, could some one of you re-sticky this thread - it is still active and popular! :sun:

I actually don't have sticky powers yet, but I mentioned it to the mods that do, so it should be re-stickied shortly.

Thanks a lot!

 

[ICD7]

For the pressure film testers- I sent out the stuff today. Got everybody from all forums except 2 as I was a little overzealous on my own testing I ran short and had to order more, so some are getting 5 and some are getting 4 test strips.

2 or 1 can be sent back for digital analysis and the balance you can use on your own account, troubleshooting, comparison etc.

I will email you guys with generalized instructions in the next day or two.

I included a couple extra tubes to compensate for the remounts.

I know it sounds stupid but this was the most complicated mailing I have ever done. You each get six envelopes. 2 donor/print, 2 sample , 1 return, 1 to hold it all...

Thanks for the update ICD7

I think this is the most complicated look I've ever taken at my heat sink applications. (So we're even )

I think this is a good time for me to try lapping a heat sink for the first time. I plan on getting impressions of before and after.

Does anyone know..... am I supposed to try and lap the heat spreader on the CPU also?

You can do, a few people do but most don't bother AFAIK, usually the CPU spreader is pretty smooth. Though I guess you could check it with a proper straight edge to check that it's flat too.

 

[ICD7]

You guys are now famous.

You are killing my averages, lol

I need some more tests to bring them up

 

[ICD7]

I also had a thought on a poorman's or DIY contact test. coat the IHS with graphite(soft pencil ?) put a piece of paper, maybe tissue paper 1.5X 1.5 in. between the IHS and sink and clamp. Should show where the CPU is making contact and where it is not. Kind of like taking a rubbing off an old tombstone or what my dentist does when matching/adjusting my bite after a filling a tooth

Might be interesting to compare to the pressure film result

bought 3 tubes from frozencpu about 2 months ago.
tried once on my qx9650, all it did was stained my cpu and lapped ultra-120 exteme, which forced me to lap both.
used Arctic Silver cleaner 10+ times, can't get rid of the mark.

by the way, it dried up superfast. only loaded it up few hours, it was already like crystal.

There's always one... :roll:

 

[ICD7]

There is a lot of ICD7 in circulation and staining is not a reported problem and of the pictures 1 or 2 pictures I have seen of reported stains were where the copper had oxidized and diamond under pressure had maybe removed the oxide

Another option- the sink surface finish may be not as fine as the particle size and the compound settled into the imperfections.

It does contain a few % carbon black other than diamond and if you have ever gotten that on your hands it does not wash off, that may have settled into the imperfections of the base. Re lapping was not necessary IMO. Maybe a better/different cleaner than the arctic clean stuff? Acetone works great for me.

As to drying out it will thicken a little under high loads but that was intentional on our part for long term stability preventing pump out. You are the only case so far out of the 1,000's of installed systems installed for months that is reporting dry out on mount. If that's what you observed that's what you saw I won't argue the point beyond the suggestions I have made

 

[kkk60091]

this is the only paste i tried so far that will stain my cpu and/or heatsink.

when you got a ulgy mark on your 1000+ usd cpu and shinning lapped heatsink, it is NOT a good feeling at all. it all happend within only few hours priming test.

I have tried tuniq tx-2, noctua nt-h1, as5, mx-1, mx-2, shin-etsu 7783d, none of these ever had this problem on the same cpu and heatsink.

they all can be cleaned by Arctic Silver cleaner easily.

You might got a great product.

I tried ICD7 once. It screwed me and I am done with it.

Pressurefilm Instructions

Key points

The test needs to come from a system that has been thermally tested with ICD7 I need to be able to relate the pressure test to a thermal result.

Ideally I would like tests from an equal number of +/- thermal results

Test is run cold - Cpu should be room temp

Take one donor and print and place the smooth sides to sink and IHS with the "frosted sides" facing each other, place on cpu and mount sink.

Wait 10 min disassemble and place print in the sample envelope provided.- Do not seal! I want to scan each one before I send them out for processing.

Note approximate room temp

Note heat sink and cpu on sample envelope. also note the number of your posted forum thermal result . Place samples in return envelope provided and return.

I only need a max of 2 per if you only want to do one thats fine. Extras are for any misfires or your own use if you want to check contact on you own

Thanks for your time and efforts

A? , I found the ICD7 fairly easy to clean off ,got most off just using a tissue & then used Isopropalalcohol (spelling?) to remove any trace amounts. No signs of drying out either after ~5 days. Are you sure its the same stuff you're talking about???
Also, even if it has marked the CPU & HS ,so what? it doesn't matter seeing as you're not going to see those surfaces all the time it's being used.

ICD7
In your table up above you're still listing me as having 1.5C increase using ICD7, this is not the case ,did you not read my follow up post? or have I misunderstood something?

Fame at last

 

[ICD7]

I can't post an image here so I am linking to a Color chart and a reference chart so you guys can do a simplified pressure analysis on your own

I'll update soon, just have not had a chance

LOL I was thinking the same thing

 

[Assimilator1]

lol

No probs ICD7 ,oh & I got my package today (quick this time!)

 

[Insidious]

mine arrived too.

 

[Cutthroat]

Me too, with any luck I should be able to do the tests on Sunday.

Note heat sink and cpu on sample envelope. also note the number of your posted forum thermal result .

I was about to run this test but forgot about that the CPU needed to be cold (don't have time to let it cool off before I go out, maybe latter), but also what do you mean by the above?

Btw going by your results list ,17 of 41 people have posted results so far for the ICD 7 test.
If you like I can PM the 24 people who have yet to post results to see if they will still be able to. Though I will need a list of forum names to do that. LMK.

Actually make that 23 as I've already PMed RaySun2Be, he mentioned that he's been very busy with RL, either being away from home or too knackered after a long day to do much about it. Can't blame anyone for RL getting in the way, though it didn't stop me poking Ray with his own cane :evil: heheh.

Oh btw ,re an earlier discussion about measuring CPU temps using CoreTemp & whether the mbrd effects the reading. From CoreTemp site

The temperature readings are very accurate as the data is collected from a Digital Thermal Sensor (or DTS) which is located in each individual processing core, near the hottest part. This sensor is digital, which means it doesn't rely on an external circuit located on the motherboard to report temperature, its value is stored in a special register in the processor so any software can access and read it. This eliminates any inaccuracy that can be caused by external motherboard circuits and sensors and then different types of programs trying to read those sensors.

Your ambient temps rose a lot with a loaded CPU!:Q, is it in a very small room or did you actually mean case temps?
Ambient temp is supposed to mean room temps.

ICD7
Once I've finished the current TIM tests & then the film test I will probably leave the installation untouched for months on my main rig, maybe even a few years if the TIM shows no signs of degredation (my 2nd rig will probably be upgraded during that time).
I guess the only problem then is will this thread still be here?, however I'm sure I'll be able to report long term temps to you as long as I remember!

Btw I'm about to test ICD7 on my 2nd rig & try the ICD7 app method for AS5 on my main rig.

I concede. Everest reports those temperatures as ambient, but yes, they are inside the case. I keep the apartment pretty cool to help save on electricity -- the computers help heat the place. Because I didn't actually measure the room temperature, anything I could say would only be a guess.

I'll do better when I upgrade the FX-60 machine. Thanks for watching over me!

 

[Insidious]

I got the pressure test done today.

I used this as an excuse to lap my heatsinks (since I had to take them apart anyway)

I want to thank you ICD7 for making this experimentation possible.

I don't have access to the X2 computer in my results thread, so I can only have 'official' results for the Q6600.

I will send the films tomorrow.


Here is a scan of my results

VERY COOL :thumbsup:
