my friend here the question is, have you ever tried that setup in push / pull from inside the case?
I'm interested cause I hace the same case I thing .. thermaltake commander ms ii, with a Thermaltake Water3.0. pro so it can show better results than my cooler does at the moment, thanks for your brief explanation about the general question!
Regards,
in my experience there is Little to NO gain using push&Pull @ the same time, over JUST push ,or Pull seperately.. Aside from spending more money, and taking up more room, there seems to be no difference( If You were to ask Me, I would tell You to Run One or the Other, either Push OR pull, but NOT both).If You want to decrease temps, and Your set-up is built in a case same or similar to mine, My recommendations are as follows...
#1 GOOD TIM, I use AS5, some say it sucks, but in my years of PC experience, I find it VERY effective.
#2 Good fans, with RPM/Flow control, my motherboard allows me to FULLY control My fans, which makes things easier, the temps i had in the images above were @ 1%-5% fans speed.(i use scythe Kaze/slipstream 120mm)
#3 Fan placement is VERY important, I use 1 low speed @ the front of my case(bottom of bezel), 1 @ the Top of My case High CFM/RPM(right above RAM/CPU) , and One pulling Cool air over My Rad( like You saw in the images above)High CFM/RPM ,It also makes sense to mention that I am running a "blower" GPU, but IME the difference between Aftermarket(dual/triple/single downward facing fans), and reference fan shrouds was minor @ best), I sometimes run a 4th fan Angled under My HDD cages in the front , facing upward @ a slight angle blowing over the GPU as well, but currently I am not. I personally run with a negative air pressure,or atleast try to, and it seems to serve Me best.
#4 finally, try to place Your Case in an area that has decent to Good air circulation,(no laying it on carpet, or stacking other warm electronics ontop of it).
#5 I run MY PSU with the PSU intake facing a vent, and the Outtake facing a vent, In my case this is upside Down, for others it might be different, just try to vent it out if you can.
I rarely break 70C on My GPU after Hours of 100% rendering, and NEVER break 65C on my CPU unless I REALLY go hard for a VERY extended period of time, and even then I cant remember a time that I registered over 75C. My Home IS central Air Cooled, but it is well over "room Temperature" or 73F.
try what works best for You, and go with the best outcome, Good Luck.
