Fan temperature controller

I've been doing some reading on these and i think its time i add one to my grow. im running 2 120cm pc fans, 1 for intake the other for extraction. When i have the intake running it can get to cold in my box so i was thinking of adding temperature controller so when it gets to hot the intake will come on for a while then go off. The price seems to vary depending what you buy, am i right in assuming that this will do the job i want it to do; http://www.ebay.co.uk/itm/Electronic-Fan-Temperature-Controler-Thermostat-Regulator-KIT-10A-12V-20C-to-80C-/281257692492?pt=LH_DefaultDomain_3&hash=item417c43cd4c

also can 2 fans be run of it or would i need 1 per fan.?

10 amp should be enough for two fans. But, you might find this setup easier to work with: https://www.rollitup.org/Journal/Entry/thermostatic-speed-controlled-exhaust-fan-using-a-variac.30771/

I dono if I would trust a 7 euro temp controller..sounds like a fire hazard waiting to happen

Often in practice requires the installation of additional heatsink of various electronic devices.Usually you have to choose between large and massive heat sink or smaller heat sink and an additional heat sink with cooling fan fan. When choosing a massive heat sink, device is expensive and occupies much more space. When choosing a heat sink with a smaller radiator and cooling fan, the fan becomes worn and dirty relatively quickly and the fan is not always necessary to work constantly. Termo Fan finds its application as an optimal solution. The device monitors the set temperature in these limits and exceeded it unblocks the relay, which runs the fan, and a fall of the temperature in the limit, the relay is blocks and the fan switches off. This leads to substantially extending the life of the fan and reduces dust in your device.
