new case time or just replace icy box unit

[davetherave2]

So I have just ordered a couple of these. https://www.overclockers.co.uk/noctua-nf-a8-pwm-fan-80mm-fg-050-nc.html they should be quiet enough and give me enough airflow to keep the cages cooler. Plus ordered an air duster as well as I think my case will need a "deep" clean. ;p
