I don't hear anything with my I3 Mac Mini. It's really calm and much quieter than my Imac. Apple may be telling people who call that it's an expected issue, but many people don't have these issues.wow I really didn't think and SSD would make noise.
I have an i7 MM and unless I put my ear against the top I don’t hear any whining.Bringing this old thread back to life...
I just got an i7 8GB 1TB 2018 Mac Mini - with coil whine right out of the box. Very frustrating. Coincidentally, I also have an i5 8GB 256GB 2018 Mac Mini for work sitting here, too. The i5 doesn't make a sound.
Is something about the i7 the noise culprit?
I reached out to Apple tech support. They had me reset the SMC - then after that didn't fix it, said it was a hardware issue and told me to return it. I'm doing an exchange with the vendor I bought from.
They typically don't. This problem is real, but it is also very much "your mileage may vary".wow I really didn't think and SSD would make noise.
The fact that large SSD's have faster write speeds has been well documented. Somebody with more tech knowledge than I can explain it better, but I think it has to do with the memory cells being closer together on larger drives.maybe this is documented elsewhere - the i5 256GB drive has write speeds around 1300 MBps. The i7 1TB drive has write speeds around 2700 MBps. Both have similar read speeds of 2600 MBps.
The Intel-i7 is likely pushing the (small , barely adequate) power-supply into a new high-utilization range. SMPS are not as stable as they reach max-output, and that power is not as "clean". This can cause coil-wine in power-supply and other components. That is why you always over-size the PS (not under-size it so it can fit in a tiny box and look pretty).More testing here since I have 2 side by side to compare.
The i5 does have some subtle noise - I previously thought it was silent. The i7 is certainly more noticeable.
This does not sound like a good solution.I’ve found a way to eliminate the coil whine when present. The coil whine has nothing to do with ssd’s as a lot of topics here suggesting. It has to do with CPU power regulation as the topicstarter already pointed out in this topic.Probably all Multicore 8th gen intel cpu’s suffer from this problem to some extend.
To make it very apparent: load your cpu to about 40% and set your sound output to 96 khz. Another way is to go to About my mac and go to the storage tab.
To eliminate it: download Intel Power Gadet , go to the menu tab Test and run “all thread test” it will run your cpu at full wattage,full frequency, and full utilization. Remarkably while power gadet and activity monitor shows full cpu utilization , all the headroom from your CPU is still available for the programs you’re running.
Of course you cpu will get hotter and the fans will be more audible after a while but it proves that it really has something to do with power fluctuations on the cpu as opposed to the ssd. It’s a probably a combination of poor quality VRM ‘s on the motherboard and speedstep fluctuations. I think apple/intel really should adress this issue as it was non existant on older generations. Another example of the eco movement go wrong
Indeed, a good solution would be for intel and apple to adress this issue. It’s more of a proof point that is related to the cpu power management and not to the ssd as many here and on the internet are thinking. It does not matter if you order one with 128-256-512 , its simply not related to that.This does not sound like a good solution.
Makes sense that it's a CPU issue as I've read similar complaints about the Intel NUC mini PCs with 8th gen CPUs.Indeed, a good solution would be for intel and apple to adress this issue.

I also would not advise this as a solution to the problem as it will probably wear out your cpu faster. Just accepting the coil/vrm whine is the best option for this problem.
