Logic board temperature sensor?
Sorry for how this post turned out to be, I tried to fit in as much info as possible but if anyone needs any other info please don't hesitate to ask.
Ok, I've ran an apple hardware test - comes up with 4sns/1/c0000008 Tsop - which I think is a temperature sensor on the logic board... However when I run Temp Monitor (off Apple site) temp readings are there for all sensors? I was going to install on another partition but the macbook still ran very slowly when booted from cd, Also there is a process called Kernel_task using between 150% - 200% cpu, performance is slightly better in safe mode however problems are still there like the mouse is very glitchy and slow it takes around 30 secs to 1 min to start any programs which are then unusable. By the way this all happened after a spill and me removing the keyboard and backlight and cleaning them both very carefully with isopropanol drying them and carefully putting everything else back in, carefully. The fan instantly starts spinning at 6200rpm the second the macbook turns on and the apple logo pops up.. Ran Techtool deluxe and volume structure failed so repaired with install disk boot and disk utility but its still absolutely trashed after less than 6 months and not covered under warranty. I just really need help with this all my work for college is on here and i need logic pro so cant use a Pc or a slow mac lol. Does anybody know where this sensor is on the board?? Or any other things that may be causing it... I forgot to mention I've also tried running the macbook without different components - battery, keyboard, display, camera, both drives and all the rest but to no avail.. Maybe any pictures showing where the sensors are or any advice whatsoever - its all very much appreciated.
Thank-you so much for all help in advance, I've recently used the guides on here to disassemble my mac and found them really helpful, Cheers guys.
