A case for cleaning the entire cooling system in your laptop

Thread Starter 
Well, I must say that earlier today I was about ready to throw my sager5670 out the windows because every time that I started a game in windows it would run for like 10-15 minutes, and then die on me (i.e. just turn off due to extream temps (80+ degrees C iirc). Also, when in linux, I had to throttle it down to state 5, 6 or sometimes 7 (the slowest state, 87% throttled), when I tried to compile something just so it wouldn't overheat. Basicly, if I did nothing it would stay around 45 degrees, and as soon as I started a compilation, it would jump up to 67 and then, semi-quickly rise to 75 where it would throttle down to 50% (if it wasn't already there), and then continue to climb. Finally, this morning, my laptop turned itself off while I was playing Deus Ex 2, and even after letting it cool for like 2 minutes (it usually only took about 20 sec), it couldn't make it though the boot process without getting too hot. So, before I made a phone call to send my laptop in for repairs I decided to take one more look at the heat sink/fan combo box so see if there was anythhing blocking the fans. (Note about 2 weeks ago I had completely cleaned the fans themselves so they were spotless). Well, for the heck of it, I opened up the fan box and there it was, about a 4mm thick line of dust was completely blocking the air from traveling through the metal fins and out of the box. Well, I cleaned that out and now the laptop is running great. I just did a 30 minute stress test (not much of a stress test, but it was enough for me) by having my system continuously recompile the kernel (keeping the proc usage at 100%) and much to my surprise, the system rose no hotting than 58 degrees C (and it never actually kicked the fans into their highest speed). Anyways, I know that it's been said before on this forum that you should clean the fan every so often, but when you do, make sure you remove the 3 screws on the box to clean the inside too.

Just in case you want to know, I've had this laptop since either the end of March or early April

Just like doing backups on a regular basis, you gotta keep that bugger clean.

I wonder though at how much dirt all these machines are sucking up. After 6 months, my 8886 had a little bit of dust but nothing serious and my performance hadn't been affected. Its been another 6 months and I am expecting the same thing, though this time I am thinking about doing the Arctic Silver routine. I take my machine to all sorts of places, construction sites, offices, the beach. How come you all aren't suffocating?

i like to keep the heatsink area healthy... it definitely runs cooler now that i use AS5, but i would really love to have the double length heatsink thats found in the 4760...

Artic Silver 5. It's a thermal compound that goes between the processor and the heatsink.

I wonder - does disassembling the fan box to clean it void the warranty?

This is why I hate the fact that I cant get to the fans easily on my 5680. It's one of the stupidest moves Sager has ever made. I am periodically vacuming the fans in the hope that this will be enough to keep the dust etc out of the fans. Of course I have already taken the step of applying a new thermal agent to the heatsink in place of the crappy one that it comes with. For those who are looking for a guide on how to do that check out the great Artic Silver guide by GelatinousFury in the 56xx tech support area. As a rule my machine never gets above 52C when under 100% cpu load.

I have heard about the guy that posted his own temperature monitoring program on these forums - Is that the way you all are finding out your own temperatures?

Wow, this has been my problem exactly. I have had my 5620 for almost 18 months now and have been slacking off on cleaning out the heatsink. Did try redoing the thermal paste and cleaning out the fan area, taking out ram, and many many other things. I just figured that the HS got clean with the fans too, but i don't have a "can of air" to blow things around, so it never really did.

I was trying to avoid asking any question about it because I _only_ run linux. I refuse to give money to any corperation that shoots first, then asks questions. (read, i didnt want to be bashed for running linux because i know that 90% of you are gamers, i get enough of that being the president of my school's LUG).

Thanks for giving me the idea and forcing my to spend 30 minutes trying to open that with screwdrivers that were way tooooo big

I am now compiling gcc without the fans going on at all.
