AS5 best $10 I spent

Just applied Artic Silver 5

Had to sacrifice a little malt whiskey and a coffee filter to get the heat sink squeeky clean

Playing FEAR, my loaded GPU temps (with fans on high using fangui) dropped from a shaking in my boots 106deg C to 70deg C

I'm on a different game level but what a difference, and it should only get better with the thermal cycling

The Dell thermal thingy looked like a tin foil stamp swimming in congealed wax.
My guess is that fear fcked it up, being over 100deg for so long gaming

Anyone out there whom has not done it, its well worth the screwdriver time

By the way it should be called artic brown not silver, the AS5 is definately brownish, I tried to leave it as thin as possible as the heat sink was very smooth as per the web instructions for AS5

I have not done my CPU as I was desperate to see the result, and it sits at 30degC idle 40deg C loaded 100% (undervolted slightly 0.716x / 1.084x13) so i wasn't planning too, but seeing the result on the GPU I may go ahead


thanks for the threads irobertous etc etc

*now I've got some temp head room, i'm gonna go back to XtremeG and the higher clocks

Hehe had that exact problem, posted in the "should I RMA the 7800" thread You need to go back in and goop a little more onto to it. The damned heatsink doesn't come close to making contact with the GPU, you have to use as5 to get it there rather then aid it.
Not to much mind you but enough so that you know there's a slightly thick layer.

The above is for the GPU, not sure if the CPU needs a different app.

Wow, that's one hell of a difference ZX81, good show! Watch your temps and make sure they stay constant (or lower) as, the AS5 "cures" (I guess that's the right word).

The CPU is a different story. The problem is that the heatsink springs dont put as much pressure on the core as they should, I guess to allow room for the thermal tape/plate/crap that Dell normally includes. I guess you could put a copper shim in there to add more pressure to the core, but it really isn't needed. The best way to put AS5 on the core is in a transparently thin layer. Spread it out and then scrape some off if you have to (use plastic, like an old credit card or microscope slide, so you dont hurt the chip). Then just place the heatsink on top of the core while pressing down gently and rotating left and right to spread out and fill in any holes/air gaps. Then tighten the heatsink down and you're good to go .

I'm at my place in Jacksonville, FL right now... and me driving across town to see friends is about the same as you guys driving a state or 2 away to see people. In Florida we're so spread out that we find it funny when someone up there says "but it's 20 mins away". You'd be suprised how many people here driving an hour or more just to get to work each day.

I wouldn't let a 30min drive keep me from getting out of the house... and on that note... need to finish up posting so I can get ready to head out for the night. =)

would adding more copper help ??

For instance...if you put a larger piece of copper on the core...and mebbe make it stick out on the outside...in an L-shaped pattern....would that actually help in conducting heat better ?

...just a thought

ahh,

back inside smoke clouds billowing, muzzle flashes, gernades and the temp up again

max seen 96deg C which is 10deg C less than previous max and is reduction range they say to expect

going to leave alone for a while and see what happens. I thought of opening it back up, leaving the old and putting a drop in the centre of the core then heatsink back on - there is so much in a tube, an experiment with enough to reapply from scratch if need be. Anyone done this? at the moment I have a thin thin coating on both as per the instructions


k6 I'm going to leave the CPU even though I have buckets of the stuff, the undervolting has it running very cool as it is

Note to anyone else that fear stresses the card more than the ati tool, not much, 4deg C more on my machine

Wow. My temps are much cooler without the mod

Hello boys,
Thought that I would add another post to an already great thread.

My system temps are pretty low when compared with others with similar specs. At idle in a room that is around 80F teh CPU is at 32c and GPU is at 49c. This is according to i9kfangui. After several hours of establishing a Greek empire in Rome TW, or trying to advance a rank in Battlefield2 the CPU is at about 50c and the GPU is around 75c. Can this be so?

I've got the i9300 upgraded with a 7800gtx and regular cooling. I have NOT overclocked and I believe this to be the reason for the relatively cool temps, and I probably will not overclock since I'm not an avid gamer and would like to keep my laptop cool to the touch when I lug it from studio to class.

K6, I'm having a hard time finding the correct gauge copper and that is the reason for the delay in doing the cooling mod. I believe that it would come in handy given that my studio is located on the 4th floor of a very poorly air-conditioned building, and I am currently living in a city located around the corner from Hades.

I'll post when I finally find some copper.

el Don

nev_neo, I wouldnt want to avert any heat of the core away from going directly to the heatpipes. I dont think one could improve on the two heatpipes that the heat from the core goes directly into, so I think leaving it as it is is fine.

ZX81, yah, that's more along the lines of where you should be . Personally, I'd open it up again and put more on the GPU core, 96C is still damn hot, hell, you can almost boil water at those temps. I bet that if you take the heatsink off the card, you'll notice that the core isn't making complete contact with the heatsink. Unfortunately you need a good amount more than just a thin layer for these cards .

Don, neither of those games are very GPU intensive. As stated, ATiTool and FEAR are probably two of the best apps to get the temps up. Here's the link to the sample pack from onlinemetals.com. I think the 16 oz. would work well in this case.

anyway of getting the heatsink for the 7800 seperately from dell ??

Seems to me that the most efficient way of cooling a laptop is to ensure that the ambient temperature is relatively low. I've had good experiences with laptop coolers in this regard. That having been said, my pinmodded 1.6->2.13 went from 45C to 37C Idling after AS5. And the fan turns on a lot less.

Look into undervolting too, my chip idles at room temp . Btw, I honestly have no idea why, but some high ranking moron keep negative repping me for this thread at 5k a pop. Grow up for christ's sake and post your problem or piss off.

Yeah, whoever is bad repping K6 needs to cut it out.
As there are people on this site that can figure out your repage and find out who you are. Enough said.

I don't think so. Because they have more than enough points to Hoff you. And you will get reported and more than likely Banned.

LoL, so many family guy references today ... did you say you would send pron

About Mr.K6 I don't think there are any regulars in this forum (xps/9300) that have enough rep and dislike him It's got to be alienware peoples.

Admin to check?
