Question mouse lag after new fans installed

[Smoker_2]

i installed 3 new 4 pin fans on my motherboard. Every so often I'm getting mouse lag idk why here is the link to the product. https://www.amazon.com/dp/B0D3QM78JL?ref=ppx_yo2ov_dt_b_fed_asin_title
I do have a 750 power supply in a Rog strix b450-f gaming motherboard I'm not using the Auro part of the fans I just plug the fans into the board tell I can get a converter

Have you unplugged the fans and tried to re-check for lag ?

yes I installed my old ones in it went away so idk i do use a fan header box for my other fan's though that came with my old fans I guess maybe to much power?
I'm just going send those ones back in get some normal RGB ones instead my motherboard don't support argb any ways

Disconnect one at a time then try it to see if it is power drain relating to the four fans.

What psu? make, model wattage and age?

its a old corsair 750 wat prob about 4-5 year old maybe less I do plan on getting a better one I'm saving up for a RTX 4070 16 gig in a psu as of next month though going put away 280 a month for a while
