Tube amps and heat

I have 2 systems in play. #1 PrimaLuna Dialogue amp with a Mytek Brooklyn DAC using Tidal. # 2 BelCanto Ref 600 Mono's same Mytek and Tidal.  I like the PrimaLuna slightly better. More separation and just the right amount of bass. The Bel Canto is very close but ever so slightly missing something, maybe in clarity separation. Since I live in AZ using the PrimaLuna with 14 tubes is difficult (HEAT). Question --- Is there am amp the will give me the sound of the PrimaLuna tube and not generate as much heat, something like a hybred. Or can I put in the BelCanto system a tube pre amp/hybred and get the tube benefit on that system as well. I've been using the PrimaLuna system during the winter, however we are starting to warm up here. 90+ this weekend and I'm afraid I'll have to shut down the PrimaLuna for 6 months or so. Suggestions anyone. BTW I just tried a Aesthetix Calypso Pre with the Bel's and didn't like the sound. I could live with it, but it's not what I'm looking for.
Thanks

I had a pair of Golden Tube Audio power amps wired as mono blocks back in the day. I sweated my nuts off in summer and got tired of tube rolling and the associated microphonics of NOS room heaters, so I sold them used at The Sounding Board , formerly in Ridgewood NJ, where I sold the High End part time. Took a beating on my price... Pretty much stick to Solid State and Digital these days,  except for my Cary LSI -80

I live in western India where summer temperature ( Highs ) is 40-46 degree Celsius (104 - 115 degree F ) everyday during day time , my tube amp is AES SuperAmp Signature 35 wpc with 4xKT88 , 2x E88CC  and 2x6BQ5 . I have A.C. fitted in the listening room. 
I have three vents ( size 55 x 55 mm each ) with holes in the bottom plate of my amp chassis and installed a fan 50 x 50 x 10 mm ( 12 Volt ) over only one vent to push the air from bottom of the amp into the amp interiors . The other two vents are without fans. More ever on the top of the amp , under each power tube KT88, there are 6-8 small holes in the metal chassis around the tube socket , from where the hot air escapes  upward brushing  the glass of each tube.  This arrangement keeps the heat of amp under reasonable control .
I am thinking to add two more fans of 50 x 50 mm under the other two vents also , but not sure if that would be too much air to blow into the amp !

If I may add: the fan runs at 12 v and quite at 30 dB under standby mode of amp and at reduced volts under "operate" mode of amp to run at 24-26 dB. So I guess adding two fans would still be ok on noise  level, but will have to find out. Any suggestions or comments  are most welcome.
