After the lapping. Almost the same.:mad:
For the love of Pete, fella's all I'm asking is that you TRY removing your side-panels for several hours and watch the temps drop. I bet you wont put that side-panel back on.
Today it's warm, but recently I've had the windows closed, because of a review I'm writing on the RBX block, I need to find temps "normal" people would experience. Although what I don't understand is I'm not so special. How hard could it be to find a window, put your PC beneath it, and open the window a crack. It's Dec in R.I. on the shoreline, and it's almost 60F outside, so I'm stting here in a Tee-shirt, so I'm not freezing. These are the temps I'm getting at the moment using the RBX block, with H20 components outside of the case.
i will do it. Here in Rio is very hot (40C).
Liquid3D, what did you think of my lapping ?
:(

and why'd you take the shim off the processor before lapping it?
Shim?
Your lapping looks pretty good, but you want to go a few more finer grits down, and in reversing circular motions. Remember to place the sand-paper on a piece of glass, or a mirror, to ensure the surface is flat. Carefully spreading your weight (using a cloth or your fingers but don't bend the pins) across the pins, go in circular, and/or figure eight (8) motions, keeeping the IHS flat on the surface. If you can't get the figure eight thing down, just go in circles, but be sure to reverse the direction. Keep cleaning the processor with alcohol, and tapping the sand-paper to get the powdered copper off. It will go much better if you keep cleaning it.
I'm bummed because I have one of the famous SL6WT Malay 2.8C's L323A832, and it's crapping out above 250FSB, or 3585MHz. Here's my OC temps now;
LOL! I used to run my Hx08 with the side panel off all the time, that was before I was OC'ing and monitoring temps. It was just a pain in the ass to take all the screws out to get inside the case to work on it.Quote:

Its fairly cool in my room here. Winter outside, and window cracked. I don't see much a difference with the panel off on my Kingwin, but I think I have good airflow anyway so. The other issue for me thou, is I don't think the P4PE temp sensors are accurate. Nobody really seems to know WHERE the mobo sensor is actually located for one thing, at least on the forums I have asked on. Several people on abxzone.com have reported goofy temps with boards shipped before January 2003. I got mine in Dec. 02.
In regards to lapping: Liquids suggestion to use a figure 8 motion is a great one. Doing the figure 8's really seems to make it easier to keep things FLAT, especially if you do it in conjunction with my Sharpie trick. Draw an X on the IHS, and then when you send you can see your high and low spots :) Also, you should probably keep in mind, the more mirror like your finish, the LESS TIM you want to use, because there theoretically less voids to fill.
thank you nailbomb, i did that lapped in figure 8 motion. I didnt appy to much force while lapping, so i am afraid of dead spots.
Hrm, you must not have sanded very much Marvin, because I can still see the X there. The way you know its flat is when all the X is GONE.
sorry the mistake Nail, i draw the X pattern, as you said, before lapping. the final is this.
Nice tweak. Do you remove IHS before lapping? I'm worry about this hole in the Heatspreader whats got happents if came dirts in?
The hole is just a leftover from the manufacturing process. When they epoxy the IHS to the chip wafer there is a lot of heat generated. The hole is there to prevent the IHS from blowing off the top of the assembly.
So, I wouldn't be too awfully worried about getting stuff in the hole, especially if you follow Liquid's suggestion of cleaning the IHS with alchohol as you do your sanding.
I got an excellent finish using a kit I got from www.EasyPCKits.com they sent me a small piece of glass, and all the paper you would ever need. At first I didn't even know what the different colored paper was for, it was so fine, it just felt like paper hehe. Here's a picutre, and on the sheet you can read they supply 400 - 1000, and then 40-micron - 15-micron paper. These are the results using fine papers;
Did 2 things today:
1. bent my Swiftech clips to get a little more mounting pressure.
2. went up to 1500 grit on lapping. Had stopped at 1000 previously
Result: -2C :)
Ever consider Watercooling my friend? You simply can't it for the money; http://www.dangerden.com/mall/Kits/kits_retail.asp
DangerDen Maze-4 Intro Kit is only $174, and is awsomw, but for $199 I'd get the Powerkit, because it includes a slightly more powerful pump, and better radiator.
The kits come with MAZE-4 CPU block, Hydor L30 (320Gph) pump, Black Ice Extreme Radiator, 120mm/92CFM Sunon fan, 1.3-Meters 1/2" clear tubing, Water Wetter, clamps, AS3. It was the best move I've ever made in my PC experience, and it's so versatile. I now use the D.D. Z-chipset, and have their GPU block as well. Just waiting for a larger Radiator. You can experience as much as a -25C overall temp drop switching to H20. The screenshots below were taken the other nite, when I had my window open about 6", and yes it was cold in my room, but not freezing. I did put on a sweater. Obviously no one would do this all the time, but these temps allowed me to do some OCing.
Yes, I have been looking at it. A LOT actually :) For some 2.4c action.
Hrm, biopsychiatry.com eh?
Actually it's more like Neurophilosophy. Neuroscience encapsulates several disciplines, at it's base is Cognitive Science, AI (Artificial Intelligence), Physiopsychology, Neurochemistry, and Linguistics. Neurophilosophy delves into topic's such as the "Nature" of consciousness. Are our thoughts purely physiochemical brain states. Such that the color green, or the thought of green, can be defined as, such and such an exact neurochemical state, at such and such a time.
Semantics, a sub-discipline of Linguistics talks about things such as "Possible Worlds" as it applies to "Truth Values." Mathematical methods in linguistics are integral to AI, and programs such as Parallel Distributive Processing, are excellent analogies for the Brain's learning process. Funny thing is philosophers have been arguing such ideas even before PLato's Allegory of the Cave. Reading THIS will most likely lead you to understand why I find this science fascinating.
I just tried lapping my 2.6C yesterday, to see if it would make any different. I used 1200 paper all the time. I don't think my temps were any better than before...i only use sucky Tsunami cooler with some new AS5 that i just got. I just think that my temps are higher now than it were with my shinetsu . In prime it got up to max 54C, with my AS5 and lapping the CPU it whent up to 58C in prime! Maybe the temps are so high now because of the goop is recently put on. I also used as little goop as i could, so you barely could see the core of the CPU.
Here is the result:
NR2.
Damn, Liquid3D, that's some fine lapping. I'll post some pics of my results soon, I took some pics but haven't downloaded them to the PC yet. I used 500-600-1200-2000 grit, took me about a week to do the lapping(my HDD was dead and I had a defective mobo, so for a whole week my only contact with my PC was when I lapped the CPU :D).
This is how cold my Danger Den water-cooler RBX and Z-chipset NB blocks got, with the radiator outside of the case, and the window cracked a tad. This is appraoching phase-change cold and Yes I did see my breath that morning hehe;
temps didnt change much. CNPS7000 Al-Cu, 2.4B SL6RZ, AS5. I posted alexandrus picture, I've had it downloaded to my PC ;)
I also did my last CPU. 2.0A, AS3, SLK900U, SCF2@1600RPM. 2000grit, both. I experienced higher temps, ~2-3C.. But after a week or so, I experienced a temp drop of ~2C of the original.. I suppose it's the low RPM of the fan. Picture will follow(sorry but a bit blurry.. about 1 year ago and shacking hands at 5AM)
and my old cpu¤t heatsink... I could read with ease the AS3 notes in my CPU..baad picture :mad:
Nice lapping job there! It's possible if you didn't lap the heatsink (or CPU) on a piece of glass you actually created an un-even surface. This would explain why temps went up. Also don't spread the paste, simply place a small dollup in the center of the CPU, and mount the heatsink.
The manner in which you lap is critical as well. If you don't continually clean away the copper particles, they tend to become re-ground into the surface, making deeper pits, so all the work ends up being defeated.
Nevin the owner of Arctic Silver told me that moving the heatsink "shift it just a bit" actually seats, and sets the paste. After about a week of applying new TIM on a CPU, you should give the heatsink a slight shift. being careful not to loosen the fastners, but enough to cause a shift in the paste, in which any air-gaps are eliminated. (he's also the person who taught me how to apply paste)
OK, thanks a lot for the advices. Actually I don't clean the surface when lapping, I like the way the sandpaper became more smooth. At the end, for the final touch, a bit of soap with water is used, I think it increases the smoothness.
I've chosen myself the piece of glass, it's near the SLK900 heatsink. I will give it a try with AS5. I always spread very well any kind of thermal paste, maybe it's time for a new approach. Happy lapping to everybody :)Quote:

just put a small dab os paste the center of the IHS.your lapping looks fine.:D
