Apple Event: May 7th at 7 am PT
So i bought my iMac with pretty good specs because i was planning on using it for ArchiCAD as well as playing the sims 4. I’ve used it barely the last month and now the iMac’s fans are noisy from when i just turn on the god **** computer???! What is wrong? It runs super slow and is Even worse them the schools 7 Year old iMacs... so dissapointed

It would be helpful to share with us the complete specs of your iMac starting with exactly which one you have. To make this easy run and post the result of Etrecheck http://www.etrecheck.com

How long have you had this “new” iMac?
The 5400 RPM mechanical spinning hard drive in both the hard drive and “Fusion drives” are woefully slow to read and write to.
The hard drives and fusion drives in these 21 inch screen iMacs all utilise 33%-50% slower 5400 RPM laptop hard drives instead of the “normal” and “ desktop standard” 7200 RPM mechanical spinning hard drives.
This means, potentially, between 30-50% slower read/writes to these drives and slower seek times!
The ONLY viable and speedy storage drive options in these new, 2017, 21 inch screen iMacs IS THE SSD drive option!
The fix?
Forget the internal hard drive (use it strictly as a backup storage and emergency boot drive) and purchase an external USB 3.0/3.1 connected 256, 500 GBs or 1.0 TB pure all SSD drive.
Install a Mac OS (or purchase and use data cloning software, like CarbonCopyCloner or SuperDuper to clone your current internal system setup) to this external SSD drive and make the external SSD drive your permanent boot drive!
Your iMac will run A WHOLE LOT FASTER than it does now from an external USB 3.0/3.1 SSD drive!
A WHOLE LOT FASTER from an external SSD drive!
Best of Luck to You!
Already reset the SMC a couple of times.
My iMac is a Retina 4K, 21,5 inch 2017 with 3,6 GHz Intel Core i7, 16 GB 2400 MHz DDR4 and Radeon Pro 560 4096 MB
Etrecheck?
I agree with MichelPM - the glacially slow hard drive in your Mac will never be satisfactory.
Almost new iMac runs slow and fans are noisy
