Razer Blade 15 (2018) 100% CPU Usage after start-up until...

I open task-manager. So, I have been having this issue for a month-ish now, where my laptop would have fans running fairly loud (which I am not used to), and the battery draining quite fast even at the 60Hz screen refresh rate. I bought my laptop on release, and it's been working great till now. To investigate the fan-loudness further, I went to check task-manager, right when I opened it I noticed 100% CPU usage, but within few seconds, the CPU usage went back low. I have tried this several times now, the laptop will be loud and have 100% CPU usage until I open task-manager, and then everything will be ok. Some threads have been hinting the issue towards Razer Synapse. But I have no idea what the real culprit is. I have checked my start-up services and I don't see anything odd;

• LGHUB
• Razer Synapse 3
• f.lux
• Discord
• Windows Logon GUI Application
• Realtek HD Audio Universal Service
• Windows Security notification icon

are the enabled applications on start-up.
