Oct 8, 2020 at 21:56 comment added Gerry Myerson @zeraouliarafik you have introduced the condition $n\ge5041$, which was not in the original question.
Oct 8, 2020 at 21:34 comment added Sylvain JULIEN This makes me want to define the "Robin constant" $R$ as the infimum of the $C>0$ such that $\frac{\sigma(n)}{n}<e^{C}\log\log n, n\geq 5041$.

Math. vol. 31 No. 1 (2007), 67–75, proved if $m$ is odd, $m>(1/2)3^9$, then $\sigma(2m)/(2m)<(39/40)e^{\gamma}\log\log2m$. See projecteuclid.org/download/pdf_1/euclid.tkbjm/1496165115
