Innovation Cooling's Diamond 7 TIM test results

[SiGfever]

Count me in for the test strip.

I think after seeing the "Pea" sizes used that I will pull the mount tomorrow to confirm spread pattern. The MX-2 had an even spread pattern (should have taken a picture), so if the D7 was not applied properly for this TIM the testing won't be fair and accurate.

[tastymannatees]

I found some pricing - Not too bad, sold by the square foot or roll - sq ft $57.00 IHS is what ? 1.2-1.3 inches? I can cut it up and send it out. Probably 2 per mount in case somebody has a misfires on the first one.

So how much is everybody going to need?

I am only doing the test on one Q6600.

[tastymannatees]

what I would like to do if possible is scan the tested result and then post along with the tested thermal results for that particular configuration which will make it easy to compare.

If I don't get enough out of this group I'll revisit a couple of the other giveaways to expand the sample I need at least 20 to 30

I have 13 potential candidates.....all quads. Coolers are, 7 Fuzion blocks, one TRUE, and 5 Zalman 9700s.

(Side note - I really love the TRUE!! What a cooler. I won't go back to 9700s after trying one out. I just wish it was 3/8" shorter. Hard to get it in rackmount cases.)

I would say minimum of 2 pieces. I would like to see the mounting preassure of the fuzion and my 6002 but still have not got the new quad put in and the e6600 out side to test yet. I will be able to get that done by the end of the week I am thinking.

it all depends on how many test you want I guess because like bob here he can put it on 13 chips so say 1 per chip and 1 or 2 extras just in case of a mess up

[tastymannatees]

A spectrum of results is good, good bad indifferent, same sink, same block whatever. And if you have a scanner handy to scan the results would be helpful.

It would be nice to generate some charts Pressure vs performance - pressure vs Cure time and maybe tag some sinks with the better pressure/mounts.

I just thought I was going to put the Diamond 7 to a tough test today - a QX6700 that runs hot no matter what I do. So.... I shut down the computer with the hot running QX6700 (my "main" computer), replaced the AS5 with the Diamond 7. Fought with that !#@$ TRUE. Finally got it all back together. Wouldn't boot up.... Long story short - I had 4 sticks of Ballistix Tracer DDR2-1000 (2X1GB and 2X512MB) die at the same time. Now I'm running 1GB (2X512MB) of non Ballistix Crucial DDR2 ??? (800 I think) and instead of being clocked at 3.55GHz the QX6700 is clocked at 3.2GHz. There's a hit on my WCG output for a couple to few weeks.

It's definitely time to get in touch with Crucial. I now have 8 sticks of Ballistix that are dead. In addition to the 4 sticks mentioned above I also have 2 sticks of Ballistix DDR2-1066 and 2 sticks of Ballistix DDR2-800 that are dead.

Sorry to hear about your D9 disaster .
What's up with D9 being dead after a reboot? I've had a set go bad like that too.

Count me in please! I'm testing on 3 systems (1x Kentsfield, 1x Conroe, 1x Wolfdale)

It may have something to do with the heat: as long as they are hot they will work, when they cool down - no boot.

So how do you mail a pressure sensitive film?

I assume if you just put it in an envelope between two pieces of cardboard just going through a mail sorter or just the weight of other mail on top of it in the bottom of a truck might activate it.

[littleowl]

now that is a good question
I would guess you would need something to put it in that will not flex in at all like a box so to speak

[G.Foyle]

Maybe put it in a small tube (like a box for photographic film)

[littleowl]

Maybe put it in a small tube (like a box for photographic film)

but when you roll it you could make lines that would set off the pressure change because your putting it under some pressure.

[s0lid]

Could somebody post me link to european webshop which sell these?

[tastymannatees]

Looks like small box is the ticket.

[123bob]

A thin CD case may also work. Then that can be placed in an envelope.

It has to hit 28 PSI in order to activate. I would think it really is a problem to send the micro-pressure stuff. It's only takes .2 PSI to set that off.

Another idea...When you place your order, ask SPI how they ship their samples. That should provide the answer.

I would love to help. From time to time I have the impression that my standard CNPS mounts aren't really applying a lot of pressure.

[64dragon]

i've been following this thread and just made a purchase with petra's for some D7 and Shin-Etsu X23-7783D to do some comparing with my AS5. when i have results i'll post em here. also made a request for some trial pressurex, we'll see what happens. i'll find out how my lapping is on my hsf and ihs.

i'll be testing on my x2 4200 cooled by a thermalright ultima 90, possibly trying my 7900GS vid card. may try it on my p4 2.8 laptop which idles at 50C and using the tv tuner its 60-70C, no theres no dust either.

I'll browse Staples next week and find something CD cases should work.

Hmmm, I started a cure test with one of my machines which was re-shuffled parts from my prior reports. This one is an IP35 Pro, Q6600, TRUE machine.

D7 applied, reasonable pea size, pic below.




Idle temps
CT idle 30,31,28,28
Ambient 22.6

Load (BOINC) temps
CT load 42,45,40,43
Ambient 22.6

I ran for 2.5 days and got the following....

Load (BOINC) temps
CT load 46,49,44,46
Ambient 24.4

Allowing for 2 degree ambient change, I got a 1 degree rise. Decided to rip off the sink and here's what I found.....

CPU side


TRUE side


How I managed to get it like this, I don't know. I pushed straight down on it, with no twisting. As we all know, it's not easy to put on the TRUE screws, but I usually start on one side, then start the cross side screw. Then I start the other corner's screws. When I get them all started, I crank a couple turns on each one in a cross pattern until they bottom out.

Hmmmmm

I took the opportunity to throw some AS5 on and try that out for a couple of days. Healthy pea blog, straight down with the sink, no twist, no squish. Here's some initial data on that. I'll update this post as it goes.

AS5 Idle temps
CT idle 33,34,31,31
Ambient 23.9

AS5 Load (BOINC) temps at 3.5 hours runtime
CT load 44,48,44,44
Ambient 23.5

Note, here my initial D7 data wins by a degree....We'll see how she cures. Then I'll go back to D7 with a slightly bigger blob.

So, it is possible for me to miss-apply this stuff somehow........

Bob,

I did the same thing as you can see in the above post. I have never had this issue when applying MX-2, it always spread even across the CPU and block. After this current "blob" has one week of run time 24/7 I will pull it again and reinspect the pattern.

Yup, I see that. Curious how cleanly we missed areas....

[tastymannatees]

Maybe that's where the twist came in at Anandtech. If you start on one side it might tend to push the paste in the opposite direction and give an uneven spread. Do you remember which side you started on?

I've got a busy week this week but if I find time I'll see if I can model it with a glass slide and a heat sink tomorrow.
