Fans run at 6000, CPU at 110° since hard drive install
I have a Powerbook Pro A1226. The hard drive was replaced a year ago. From that moment on, from the time I first turn on the computer, the fans race at 6000 rpm.
I know this only after I performed SCM twice, PRAM (which did improve the speed which was already fast), couldn't run the AHT because I don't have the disk and it's considered an antiquated model by Apple's standards (please don't anyone inform me how to get that downloaded because you cannot with the 2007 Santa Rosa). I ordered the disk from Apple ($18.00) but no telling how long it will take to get here and I need it fixed by then.
I downloaded the iSTAT and that's how I know the temp of the CPU and the RPM's. BUT...there's no temp reading for the GPU. Why?
I've opened my machine, blew out everything and performed the inspections for cable connections except for the 2 thermal sensors which require a complete tear down to get to (left fan and middle thermal sensors).
Here's the 2nd question. If both fans are running, the likelihood that both sensors are out seems bizarre to me. Would it not be sensible to think that the middle sensor is the one which has gone capoot? And why would the GPU not be registering a temperature with iSTAT? And even more bizarre, why is the sensor registering 110° right after starting up with no load? Even after running several minutes and I do nothing, it achieves 114° then down to 90° then back up again.
Looking forward to recommendations. I'm attaching a screenshot of iSTAT after a few minutes at idle with no open programs. OOoops, well, I would attach an exceptional screenshot but iFixit states it doesn't meet their minimum of 592 x 444 whatever that's supposed to mean.
Ist dies eine gute Frage?

Spoke with Seagate tech. NOPE, no such thing as jumpers for this year of Mac. He stated that Mac is specific with its hardware and that placing a 7200 drive when the original is 5400 is like putting a 4 cylinder onto a 4 barrel vehicle (WTH? or is that the other way around?) Ha! I'm a girl.
Appears that the long and short of it is that I'm looking at buying a different hard drive. Does iFixit want my current new hard drive with the 5-year warranty??? Thank you much for your help, hope this conversation helps others in the future!

Don't know on what planet this tech support person is on, there docs imply they have a compatibility jumper. Did you point out the doc I have linked below to him? It's possible the newer rev of the drive no longer offers a jumper which would be a different story. As to the rpm of the drive that has no bearing, it's the speed of the I/O channel (SATA speed) that does, i.e. SATA I, II or III. If they can't get you the needed jumper you'll need to find a local computer repair person to snag one.

Remember this is a replacement drive, not the original drive which he maybe thinking.
