z1sp fan noise episode II

[paradoxchild]

hello, not too long ago i posted the following

http://www.club-vaio.com/clubvaio/mvnforum/viewthread?thread=32540

and was advised to get some compressed air and clean my laptop's vents.

i was all set to do this when the noise suddenly stopped and, being not the most confident with technical things, i decided to leave well alone.

a mistake. yesterday, after months of no noise, during a virus scan the noise returned, only much worse! i know that virus scans are processor intensive, but the noise was so loud that i cancelled the scan and shut my vaio down. i have not dare turn it on since!

so, i am now going to try the compressed air , but i am a little unsure what you do? sorry if its a silly question.

on the underneath of my vaio are 3 vents, the top left one appears to have the fan ..am i ment to spray the air into those holes or should i remove the underneath itself?

i just thought that blowing dust in such a confined space will just blow it somewhere else, rather than out.

its not under warrenty anymore so i'd like to try all that i can before having to spend lots on having sony do it.

thanks

jj (again)
ps apologies for not doing the compressed air before

Hi paradoxchild

36-43c is an improvement on 48 to 62 (when in idle) temps reported in your previous thread, looks like the compressed air may have helped..:smileyhappy:

[paradoxchild]

yes thats true, i hadn't thought of that. should i also have blown the side vent where the warm air comes out? i concentrated on the underside to be honest.

what is a 'good' temp when in use? i thought mine still seemed a bit high but i guess the applications i was using were quite resource hungry

[kee-lo_]

You should definately do the side one, this is probably why your high CPU usage tempretures are bad

[paradoxchild]

oh ok sorry. will do it the next chance i get . i'm disabled so need help. thank you for your help and patience

[kee-lo_]

No problem, I am disabled too

[paradoxchild]

hello, i have done the air in the side vent, and using the same ammount of applications etc, the maximum usage temp is fluctuating between 68-70c which is better than the 74c before. is that ok or still high though?

one thing i did notice was that using mobilemeter, the hdd temp went from 0 to 46c and then to 0c..i didnt look at that the 2 other times so i dont know if its significant. (ie ive no idea what it means lol).

[paradoxchild]

i just closed a few of the most intensive apps that i was running, and the temp dropped to 49c but the hdd shot up to 51c! is that because the fan stopped? or have i caused a problem elsewhere

[kee-lo_]

Sounds like a big chunk has moved, if you can see a local technician to help you open it for cleaning then that would be the best move

[paradoxchild]

sorry i'm not sure what you mean. did you mean a big chunk has moved shown by my lower maximum usage temp, or shown by the hdd temp?

[paradoxchild]

if its a case of having to, is it possible to use the compressed air on the hard drive? between us, my dad and i could remove the keyboard as you would to add memory. would the hdd be visible then?
