Nanotherm-
I don't usually give high praises for a product but this certainly warrants it. Here's my results with 2 different 8rda+, amd xp2100+ with slk800 and tt sf2 systems at 74degree ambient temps:
System 1
vcore 1.95
fsb 228 @2.5ghz
artic silver3 load temp 50C
nanotherm pcm+ load temp 42C!!
System 2
vcore 2.175
fsb 218 @ 2.5ghz
artic silver3 load temp 51C
nanotherm pcm+ load temp 48C
Thanks Nanotherm for a great product. Any of you still on the fence about this product, it's a must try!!
I love the PCM+ too, but there was more going on with system 1 than meets the eye....8c drop? Your heatsink must have needed to be reseated, dust blown off HS or something. No t-grease alone will give you that much of a drop. I got same results as you did with system2.
It goes on nice and easy doesn't it? :D
I agree that there must have been an issue with system 1 but it had been running at that temp for 3 months despite reseating and cleaning the hsf. At least I'm fairly sure it was seated properly as I always swivel the heatsink a little after installation to be sure it's not caught up on something. Just not sure what made the temp drop so much as I didn't even clean the dust off when I used the PCM+
Whatever it was, I'm not complaining :)
Don't take this wrong... but that might be the problem. It shouldn't be moved after the 2 surfaces are mated. It could cause problems, the worst being cracked or chipped AMD dies.Quote:

Please don't take thius as a personal attack, but I must concur with The Dude. Everytime you "swivel" the heatsink your effectively spreading the paste to area's where it's not required, and there-by removing it from areas where it is.
I don't know about you, but I use the thinnest coat of any thermal paste I apply. Too much paste defeats the purpose. It should be spread evenly covering the entire surface, however; NOT over-flowing onto the core edges. Albeit only a few mm in height, the core edges dissipate a great deal of heat.
if your were to measure the surface area of the core, and then measure the total surface area of all four core edges, I think you'll find those edges total area is comprises as much as 17% as the top area. That's a significant additional; area from which to dissipate heat. Now what's critical here, is that heat escaping from the top, would IDEALLY be dissipated more rapidly then heat from the edges, HOWEVER; if there's too much thermal, paste, or your case ambeint temps becomes too high, or any number of scenarios which may slow that process, then the sides begin to dissipate more of the "total" load. Since the internal's of those edges may come in contact with circuits which operate at a higher temp then other's, they must be left unobstructed. This is why many people remove the shims from their NB. The shim inhibits airflow, and "trap's" a pocket of air around the sides of the chip. So with the CPU, those core edges, that few mm of area, has a tremdendous amount of heated air around it. That air should be continually circulated from underneath. That why heat sinks like Dr Thermal, and the higher-end P4's now, are designed so that the plate is only slightly larger then the core. The fin design is cut right down to the bottom of the heatsink allowing the fan to move away that heated air eminating from the core edges.
Just imagine the heat coming off theose edges in the picture below. And try to imagine which circuits may reside against those edges in the photo. It's a significant amount of space. When you "swivel" the processor, your forcing paste over those edges, like throwing a blanket over the sides. ;)
Wow.....look at that lap job! :D
Thank's :) here's a better, Reflection-shot. I was thinking of doing it as a goof, like a photo shoot. "P4 in the nude" ya know, place it on a silk pillowcase, with a rose....
(you can see my Prommie in the background awaiting RMA :( )
Not bad. My pcm is still idling at 39° which is a 3°c drop at idle compared to AS3. At load it is roughly a 2° drop. I still have the initial application on as I have not had any time to reapply it lately.
I know my testing is not totally conclusive nor proffessional, but atleast for me it shows PCM is some good §§§§e!
We certainly all the (positive) feedback - thank you. :)
Thanks for the heads up regarding swivelling the hsf. Makes sense to me. On my next application I'll do it right!
Liquid3D - Have a look at this photo of a P4 without the heatspreader. There are no circuits residing against the edges of the heatspreader. Truth be known, the heatspreader is more of a core protector. The vast majority of the heat goes straight up from the core to the heatsink.
OMG I forgot about that, in fact I've seen those pics the first time I read a "removal of the P4 heatspreasder article". I am the biggest Ass on the Internet.
Oh well Humility, through humiliation. Not the most comfortable method of learning, but none-the-less, quite effective. Thank's for posting that. I'll have to change my reply to a thread over at LowYat. SHeez.
:p:
By the by, it seems like an awful amount of hot air would remain trapped under there? I wonder why it dissipates heat so well, compared to removing it? From what I've seen thetre's only a 4C drop in temps after people remove them. Do you think a SLK900U with the mobo "board" mounting kit, would be too much pressure for that core?
They are usually mated to the IHS pretty good, even if it is POS silicon stuff they use to do it with.
Swiveling isnt good, but pressure to squeeze out excess TIM is. Just dont overdo it or have more on one spot than another...
Also remember AMD's and P4's will not react the same to pressure, because of hte surface area the TIM is covering...
Try this: Take a P4 and press a peice of hockey glass on top of it so you can actually see the TIM spread out.. and pressure points. Gotta make sure to use really steady glass, though, 'cause you dont want it to shatter in your hands!
I should get my "thermal testing unit" set up.... all my stuff is in except for the mobo and ram 8-/
You guys rock!
I reapplied the nanotherm using a baggie, this time not swiveling the hsf. Temps dropped 3C!!
Thanks all!! :D
We're now supplying "finger cots" (finger rubbers) with the new Nanotherm PCM+ product kits, which will further enhance the ease and convenience of achieving a proper application with the PCM+. Anyone on this forum who has already purchased the PCM+ product should pm me with your name and mailing address and I will personally see to it that you receive a free finger cot to make your next application really smooth. And, yes, all personal information is kept absolutely private and confidential, as is our policy. It's just our way of saying "thanks" to everyone who has supported our new product ;)
heh, reminds me of the "finger condoms" you get if you slice yourself in the foods course I was taking...
You got the right idea! The 'finger condoms' are certainly a much more effective and efficient way to apply TIMs that the old "plastic-bag-over-the-finger" method. Heh, we're always thinking about how to make things newer, better and easier for you... it's what we do best ;)
Hey I should get a royalty! :stick:
Bah you are a smart man and sure you heard of the baggie before I said it to you!lol I need to find a better way to cash in, hugh!heheh:D
BTW that sounds like a great idea. One more reason PCM is a great buy!:banana: Plus my wife won't get mad at me messin up the saran wrap for one little piece.
I think I'm going pcm for my next TIM purchase. If nothing else, just for the customer service. I mean, my arctic silver 3 and ceramique have been good, but noting ground breaking.
Hey Scott, I agree with SandMan. I think it's great that you are doing this as service to your customers. Working as a manager in retail, customer service means as much as a quality product. To me, you have both, and this will ensure me staying a customer! Thanks again.
Thanks guys - we're pleased to be of service to you. Quite frankly, without you, we wouldn't exist...
Everyone loves a man who gives away free condoms! :D
Do not carry one of these in your wallet guys! Might give the ladies the wrong idea if they should see it. Size does matter.
LOL
did someone PM me and ask "who Tim was?"
now that has me laughing my arse off!Quote:
