3/8/2023 0 Comments Replacement for istat pro 2017![]() I'm not a hardware person, but would Tekserve have been able to replace the battery without noticing any dust in the rest of the machine? Second, I'm pretty sure that, if I had noticed the fans revving up immediately after the HDD was replaced with an SSD, I would have taken the Early 2011 MBP back to Mike's Tech Shop. First, I now remember that I had Tekserve replace the battery in my Early 2011 MBP in 2014, because digging the MBP off the floor for a one-shot offsite use revealed that its trackpad no longer worked because of battery swelling. P.S.: I've since remembered two facts that tend to rule out the possibilities stated in the preceding two paragraphs. I can't believe that the people at Mike's wouldn't have blown out the dust when they did the drive replacement, so-unless they screwed up the replacement operation-that doesn't explain why the motherboard failed 6 months later. The current boot HDD in my Mac Pro still works after 13 years of use, and the end-of-1989 HDD in my SE/30 still boots after a second flick of the power switch-although I stopped using the SE/30 except for special occasions around 2010.īut the fans in my MBP started revving up after I had Mike's Tech Shop replace its dead HDD with an SSD. I'd tend to agree with you, dal20402, about the failure of the HDD in my Early 2011 MBP after less than 3 years of actual use. If you disable Turbo Boost and are getting high temps and fan speeds, either you're doing something serious on the GPU (in which case messing around with CPU voltages won't do anything) or something is seriously wrong with your cooling system or firmware. ![]() Of course, I try to avoid doing that on a laptop, but sometimes I don't have a better option. The 56% boost in speed comes at a price of more than 3x in power consumption.įor non-critical overnight testing, I prefer to disable Turbo Boost just to preserve the laptop a little. These CPUs run much more efficiently at 2.3 GHz than at 3.6 GHz. If you have turbo boost disabled and start a heavy workload, the CPU will run at 2.3 GHz, fan speeds will stay at 1200 RPM, and temperatures will stay at around 70 C indefinitely (even all night). It will alternate between 2.3 GHz and 3.6 GHz so that the temperatures stay near 100 C and the fans stay around 7000 RPM. When the fans start to reach their max of around 7000 RPM, the CPU will start to intermittently throttle. ![]() When the CPU temperature starts to get close to 100 C, the fans will start to spin up from their base RPM of 1200.ģ. First, the CPU temperature will start to climb towards 100 C or so.Ģ. If you have turbo boost enabled and start a heavy CPU workload, the following will happen:ġ.
