Not knowing which CPU you have (Intel/AMD) the temperature at 57 looks a bit high (very for Intel) as does the 43 temperature if it is the motherboard. At the same time your fan speeds seem low unless that on the CPU is one of the low speed, high volume variety.
To help, my maximum temperatures under load at this time of year using Everest Home Free are:
CPU 51 (AMD)
Graphics Cards (2 off) 56
Motherboard Chipset 8800
The voltages look reasonable but I am no expert so have difficulty there.
