m1530 overheating - anything else I can do?

Hello, so I have the infamous overheating m1530. I have been reading around on this tremendously helpful forum and have taken several measures to cooling my laptop. Here is what I have done so far:

1) cleaned out fan and heat sink
2) applied AS5 to both CPU and GPU (also tried AS ceramique, AS5 wins as it should) (also, I did contact tests to see if my chips were making full contact with the plates, which they are).
3) undervolted my CPU (even at 12x I am stable just under 1v)
4) ordered a revision 1 heatsink (I currently have the poor metal alloy one, but should rev1 be a source of hope?)

I still get some ridiculous temperatures, though, believe it or not, much improved (in a cool room with end lifted for good ventilation):

Idle: Core0/1 = 50C GPU = 66C
Load: Core0/1 = 81/83 GPU = 95! (AS5 improved over ceramique too, lol)

Anyway, I dont have the option of getting any parts replaced as I have been out of warranty for a while. Is there anything else I can do to take these ridiculous temperatures down? I do not wish to use a laptop cooler plate since that really takes away from the portability of my laptop. Thanks mates.

 

I must bump, is there any merit in doing the "copper mod" on the m1530 CPU/GPU or is that m1330 only?

 

That's very a high temp ! I believe the heatsink is damaged, or the fan isn't working. Try not to use it until it's fixed , else it would damage your parts.

 

I received my revision one heatsink and installed it using AS5 and I must say I am very pleased with the results (using the same test conditions/length as before).

Rev 1 Heat sink Temps:
-----------------------
idle: Core0/1: 45C/45C GPU: 60C
load: Core0/1: 63C/69C GPU:75C!

Yes, thats right, revision one heatsink dropped my max load GPU temp by 20C! From everything I have done to drop the temps, the Rev1 heatsink has been the most significant. I purchased it off ebay for $19 USD, just make sure to contact the seller and make sure they sell the exact heatsink that is pictured. I have to admit, in a twisted way, its been fun trying to cut the temps down. Regardless, I dont think I will be making anymore dell purchases anytime soon.

 

before:
Idle: Core0/1 = 50C GPU = 66C
Load: Core0/1 = 81/83 GPU = 95! (AS5 improved over ceramique too, lol)

after:
idle: Core0/1: 45C/45C GPU: 60C
load: Core0/1: 63C/69C GPU:75C!

That's surely a nice difference from what you were dealing with above.

How long were you out of warranty for? The GPU warranty on the 1530 was *extended out an additional* year, outside of your normal warranty coverage. LINKY

I did not know about that extension, thanks. I use my LT regularly, so sending it in would be bothersome for me. Do you think I should send in for a replacement even though I am happy with my current temps? I have no idea or way of knowing how much the life of my components were effected.

 

It all depends on what you really want to do. I've had 2 GPU failures on my 1530 w/in 1.5 years...

I know you are happy with your current temps now, and you will be *constantly monitoring* them. This could very well happen again, may not.

What you should do is calculate how much of that *extended warranty* is left on your GPU, that is offered to us 1530 owners. And, take into consideration the *hassle* of sending it in. You also have the means of bring the temps down, as needed!

I think, I would possibly watch the temps over the next several weeks. And, if the temps overheated again like they did, I may take some action.

It seems like you have a lot more experience than I do. Are you suggesting that temperatures can increase over time from where they are at now? I did notice that after applying AS ceramique that temps slowly crept back up over two months, which is not a AS characteristic. Anyway, I was always temperature paranoid but the m1530 has really beat it into me even more. I will keep a close eye on temps and the new warranty window.

I also have a random question for you since you seem to be in the know, are your core temperatures also mismatching by a little? At lower temps my cores match and at higher temps they mismatch but I cant remember if they were like that when I first got the machine. I know sometimes you might not get a complete contact between the chip and heatsink contact. I did a test dry run, and to the best of my knowledge, there is a complete contact (though you can never tell with the crappy heatsink system of the m1530). Thanks.
