Is it ok to use as5 in place of blue thermal pads?

Ok, quick scenario description, I took my cpu heatsink off to put as5 on it. But on the other end of the heatsink piece, there was a blue spongy pad attached to this...other chip (not sure what it is), however the blue pad kind of ripped. So I just took the pad off and added a decent bit of as5 in place of it. Will that work? Or is it an ABSOLUTE must that I put a pad in that spot instead? Ok thanks!

 

not really necessary, I took mine off on thinkpad, just make sure they are in good contact

 

So, from what I gather from your post, you just took it off and that's it? Did you add anything in between to fill in the space?

 

since the blue pad seems kind thick, i think you need to put back the blue thermal pad. if you use as5, its suppose to be really thin. you would want your heatsink to touch the thermal paste at least or it wont really do much for you.

 

I did notice that the pad was a bit thick, so I added more as5 than I normally would onto a cpu/heatsink gap to fill in the space. What chip is that anyways? I wonder if I can monitor the temps on that part.

 

no you cannot use as5 in place of the blue thermal pads. LEAVE THEM ALONE.. only apply as5 to the gpu / cpu die nothing else. those thermal pads are nice and thick to allow them to make contact .. there is no way you will get as5 to work properly if applied that thick and it will prob just either make a huge mess or ooze out all over and possibly short something out.. since it is semi conductive

how thick did you apply the as5?? as5 is supposed to be applied as THIN as possible.. you will usually see these on the mem chips of a gpu or similar..

 

I did the as5 on the cpu with the normal thin amount. For the thermal pad part, I put more than usual to compensate. So far this is day 2 I'm using the comp with as5 in that spot. No problems yet, what program can I use to monitor that particular component?

 

I took the thick thermal pads off my desktop 8800gts and put ac5 on it. If the heatsink contacts, then it is fine.

 

IOn these laptops I think the space between the heatsink and the chipset is too much to just ust past.

 

Even if you use a very generous amount? I'm talking like about 1.5 milimeters thick (that's quite a lot in this case....I think)

 

I don't think you're supposed to put a thick amount of paste on. What the paste is supposed to do is fill in the micro groves between the two contact surfaces, which would lead to good thermal contact. With too much paste, there won't be any contact between the surfaces which isn't good.

I am not sure how thermal pads work, as they are made for heat transfer between larger distances. My sugguestion is to try and buy a sheet of thermal pads and use that.

 

Well I used everest ultimate, and the temps that I can see, they're mostly in the 40's. Except for one that's in the low 50's. So I'm assuming I'm safe....for now. If I do have to go with the thermal pads, what is a good recommended...brand? type? I don't really know how you classify those.

 

Do you have any idea of where to get a sheet of thermal pads. I'm interested in knowing because I plan on upgrading my cpu in my P6860 and now that I'm reading all of this seeing a potential problem.

Yes you can get them here.

Those pads aren't specified for cpus (or at least not in the terminology I understand) but I assume any size pad works eh?

 

Thanks..........those should do the trick.

the paste is supposed to be like .0004 mm thick.. lol if using as5 ESPECIALLY.. that needs to be that thin to work right

 

If you want to walk in somewhere, and buy thermal paste and pads I guess radioshack sells both fairly cheap.

Question: Is there a variety of different "quality" thermal pads? Maybe some better than others?

 

All of the ones that I saw were for cpu/gpu. None of the ones that I saw had any heat dispersion rating or anything. Just the thickness of the pad. If there is a brand difference, then teach us which is best. I'm all ears. I've got to get this stuff soon due to the fact that I have a t9300 on the way and if I don't hear different I was just going to buy the thermal pads and paste from RadioShack.

The AS5 is like $9.00-$12.00 at radio shack, as for the pad over the gpu, just be carefull

 

In case there is any confusion, the pad I am specifically referring to is near the cpu. It's not the pads on the gpu (hell, I can't even find a guide that teaches you how to get to the gpu for this laptop). The cpu's heatsink extends out to another part of the motherboard, I believe that is the chipset. That's the part I'm talking about that originally had a pad there.

 

if you can get contact without a thermal pad, I say take it off. The pad is a cheap man's version of paste in that case.

 

This link talks about replacing the cpu in a P6831 but the p6860 is the same chasse so I imagine it is the same. I goes through all issues including the thermal pad.

Well, I took a look, of course it's ideal not to tamper with anything that isn't part of the original plan, but mine somehow was attached to both ends quite evenly and resulted in stretching and tearing, so I'd had to settle for my method. So far with hwmonitor, none of the temps listed ever pass 50 (just doing regular stuff in windows, nothing demanding) so I assume the chipset is one of the temps, and it's ok.

 

I had a hard time with Arctic Ceramique, it was sticky and no matter what I did, it would stick to the dispensing tube. On the Arctic website, the instructions tell you to use a thin line. I couldn't get it right and finally just left a messy pellet size amount on the cpu

 

When I replaced my cpu, I applied as5 to the chispet as well, because the pad became a mess to reapply. I used just a tiny bit more paste than I did on the cpu just to make sure and when I was cleaning today I took the heatsink off again and there was contact between the heatsink and the chipset.
In the next week or so, I'm gonna dissasemble the laptop and see if its possible to put as5 on the gpu safely. I'll make a guide for it as well, since I know a lot of people would like to do that if its possible.

Edit: By the way for those of you who are curious about temps, they really didn't change using AS5. Gateway actually did a pretty decent job applying the thermal compound to the cpu, it wasn't globbed on like a lot of computer sellers do. My clevo m570ru Had globs of thermal compound on it, but the gateway looked like it was applied by someone who knew what they where doing.
My whole point to saying this is, those of you that are thinking of applying AS5 to just a stock cpu and not do any upgrades, I would say its not even worth messing with.

 

ARIGATO URAHARA! I mean, thank you bwhxeon!

 

i was specifically refferring to where the soft blue pads are.. those are far to thick to use as5..

 

What blue pads? The chipset had a thermal pad that was marginally thicker than a thermal compound application. I haven't seen the gpu heat pads yet, maybe later this week.

 

It's pretty easy, just take off the cpu heatsink, and bam, on the opposite end of the fan grill, there's the pad area I am referring to. Probably no more than 5 minutes to take it off, check it out, and put it back on. And the pad didn't look that thick, I'm sure my application of as5 was more than enough....I hope.

 

Update: I got my T9300 and installed it without a hitch in my P6860. Reading this thread made me a little paranoid about that thermal pad, thinking that it was going to rip it when I did the upgrade and with no replacement thermal pad I was going to be in trouble.But, I'm here to tell you you can avoid ripping it by being careful, and the screws are all numbered, take them out in order, that may be a part of it.

Grats on your t9300, do you feel any noticable difference?

 

Bigtime difference; One of the first things I did was to run 3dmark06. It gained allmost 1400 points Just by dropping in that T9300 (just shy of 9000 with stock drivers). All of the games that I play now run at Max Settings with very good Frame Rates. I don't have numbers on hand but the games seem to load faster as well. If anyone reading this has Itunes, deauthorize your computer right before you do the upgrade. Because if you don't, Itunes will think it is a new computer when you run it after the upgrade.It's not that big a deal if you don't, but you'll use up one of your allowed computers, If you just sign in. I'm sure that you would see a even bigger difference with one of the Xtreme processors but, with the T9300 the difference is very noticeable and you can get them fairly cheap if you look around online.

Gratz buddy, that is awsome.

 

Well I guess at the end of the day, it's ok to put as5 in place of the pad as long as the grease makes contact between the heatsink and the uhh I guess chipset chip. No crashes since, no freezing, no bsod, no decreased performance, etc.

 

I saw this today, finally the OP answered back, got some strange posts waiting.
