Innovation Cooling's Diamond 7 TIM test results

[SiGfever]

Not to go off topic, like that could happen in this section.

But Mr. Tasty, how would you like to crunch for a dedicated and committed (or should that be...needs to be committed) team?

[D_A]

Jeez, Sig ... you took yer time.

I didn't want to scare him off before we got some cred.

[littleowl]

Sorry Andrew I didn't have time yesterday to do the testing I will get it done this week some time and get it out!! I Will also post here when it is sent.

Sorry

[64dragon]

just got my package, thank you tasty

This is the 4th invitation. You guys running some kind of cult thing here? I am not sure I would join any club that would have me as a member
Maybe in about 6 months. I am a little busy and have several projects going on right now.-Thanks for the offer

Hey, they let me join so you know that the scale is not set very high. Cult of the Crunchers...has a nice ring to it.

I have switched to "Real Temp" program for all my temp readings as the TJunction is more accurate.

v2.55 works well with Vista.

Graysky: Maybe I should rename the Idle calibration feature because for a lot of users with low load temps, the Idle calibration feature will effect your load temps as well. That is not a mistake on my part. The reason for this is that according to my graph in the documentation, the DTS is only linear with changes in core temperature within approximately 35C of TjMax. At your load temps, you are outside the range where the DTS is 100% accurate so you still need a slight calibration factor. I have a couple of minor fixes to do and I also plan to add temperatures to the Tray icon this week to keep the fans happy. After that I will do some more extensive testing to see if the idle calibration feature needs any adjustments. I know it is very close as is if you select the right factor but I also know it is never going to be perfect because I can't test every processor. It will definitely help get your temperatures closer to the truth.http://www.xtremesystems.org/forums/...&postcount=946

The program author if I am reading this right says if you have a TjMax of 95C and you subtract 35C anything under 60C falls into a non linear range which varies between processors? So what remains is the Intel tolerance on the linearity under 60C. I have noted indicators that suggests this could be as high as 5C. This is probably close enough for fan speed control for Intel's purposes, but not really for an accurate TIM or or even heat sink comparison.

For what it is, if the guy can get the non linearity reading down to couple of degrees would be pretty good - But I would bet that with my averaging where some read high and some read low I am still closer to the actual number

used up my pressure films last night but can't seem to get a good pic. haven't uploaded them to see if they're better on the pc but i doubt it.
i was very surprised at the results. seems i have a pressure issue with my TR ultima 90, i already had 1 washer on each screw but showed very little pressure. moded in a 2nd washer and got much better results. i'll have to start thinkin of a way to replace the current mounting method or if i can replace the screws with threaded shaft(or cut the head off a screw) and use some kinda nuts to tighten down on the springs

Depends on the contact, if you are evenly distributed and the pressure/force load is spread out the impression may be lighter but the contact may be better.

I think you should just upload them to us that way we are not guessing what is going on.

[64dragon]

fine fine, i'll post pics before you guys pull out the pitchfork's and torches.

for those of you that didn't do this yet, don't hold the 2 films together in your hand/in between fingers. i ruined one of the films that way

heres what i found when i pulled the heatsink off


cpu side


once i cleaned the paste off there was a ring left on the heatsink and cpu, heres the one on the heatsink. no matter what i did nothing got it off


first pressure film, i left the case horizontal, it looks marginally better in person, camera didn't want to focus on it


second film, this time i turned the case up how it would normaly be. i have no idea why is so dark, i took 5 or 6 and they were all dark too


third film, modded the cross piece that holds the heatsink down adding a washer to it so its applying more pressure

[littleowl]

That is interesting! What was your temps before the first preasure test?

[64dragon]

i forgot to get idle temps right before but WCG load was core 1: 40 and core 2: 34
i guess i found my explination why the core temps are so different, i don't have even coverage and pressure. forgot to mention, the cut corner relates to the gold corner on my cpu. also, for the 3rd test i rotated my heatsink 180 and that seemed to help even out things

Why not send me back the first and last test samples then we could compare the temps before and with improved contact. The third one looks pretty good.

Poll - what do you guys think of the Raw contact film as a diagnostic tool for contact/pressure issues?

for pressure, yes. contact, not so good.

[tastymannatees]

Interesting, I thought your raw film was the best contact wise, it at least showed a full contact pattern.

We will see when the final results come out but that may be a more important factor than pressure and obviously some combination of the two but contact would seem to carry more weight than pressure.

[littleowl]

I find that the pressure testing to be interesting because I have noticed that people with bad contact seem to have better temps because the past fills in fully but the people that have good contact seem to get ok temps because they have a much better contact.
I think all of it goes together and is just as important.

[64dragon]

i think its fairly good at both, once you get the analysis done on the film you get a good idea of what kinda pressure your applying. i thought i had good pressure but after seeing that first film it was apparent that i didn't. the film also gives a fair idea of how your contact is because if it isn't red after then there is no contact there on a direct contact to contact scenario, this is why we use thermal paste though, because its extremely hard to get both bases completely flat. also, if both surfaces were completely flat the metals should theoretically fuse together.

Probably one of the most asked questions on the cooling forums is " I just installed X sink and my temps are still High, higher etc." and usually the first response after "did you use thermal paste?" the 2nd is "Your contact is probably bad, try remounting your sink"

I guess from most from the beta testing about 90% fall into the "good enough" or "I am getting somewhat the result expected" Though some number is/are not satisfied, they lap, buy secondary hardware, penny shim jury rigs.

So for the more rabid users the raw film does perhaps provide a general snapshot of whats going on? Enough maybe to troubleshoot a non obvious problem, light pressure, mounting pressure bias, flatness?

I am thinking of maybe blister packing a few tubes out of each lot with some film so prior to using the paste so people could optimize their mount. 3 tests per pak. probably add a couple dollars to the cost. I was wondering whether it was worth it?

I would offer it as an option so the user can choose to test their mount or just buy your paste. This way your TIM will be price competitive.

exactly. for example, the new heatpipe direct touch air cooling heatsinks. thats why i said the raw contact film is good for pressure but not so good for contact testing.

Here is a contact issue I believe, he saw higher results, yet overall pressure was pretty good.

I would like to see more results to establish a more concrete pattern before definitively saying it's this or that but contact seems to be more of a factor

[G.Foyle]

In my case the pressure seems to be very high but contact is very poor, only on the edges, not even in the center. The film is good, but the only action you could take after finding the problem is lapping, and not everyone wants to lap his CPU. Anyway such blister packs might be a good idea.
