i think it would be better to use more rads than add more fans or better fans.
also RX360 is made for low speed so as long as a cheap fan there running low speed, the performance is good already. Actually once the fans are above 1000rpm many other rads start to be competitive as the RX
you can always use AC PWM fans, may not be so good as GT in rad position but at RM19 each now who cares. With GT the difference is around 1-2C. are you willing to pay additional rm37 each to get a marginal improvement. there is a thermal headroom for a single rad. GOing faster speeds would not be so beneficiary then

i do feel doing a single loop in your case would be better use of the both rads more efficiently
using a 480 for cpu would have some extra thermal headroom to spare for the gpu

well i guess you need to go for GT or delta fans with headphones and the air con

i think it would be better if u ask for feedback here, people will respond. This way you can learn and continue your watercooling journey

based on my experience with the rasa kit, the pump is weak. You should have cut the tubing going back to the pump


you can get the waterblock for the 560 from either ezzy or jibek. after the cpu block, route the tubing into the gpu block.
You would need to change to a better pump and put in more rads though. I think you should get the mcp655 low noise and high reliability
on a single rad the heat from cpu and gpu would be too hot even for a rx240
what chassis are you using?

changing to a d5 would be better compared to the stock rasa pump. Based on my experience. But using more than a d5 would not do much for now.
Too many restrictions for the rasa pump.

maybe the same too because of mcp355 heat dump
655 has last of an issue with heat dump

what you did not mention is your fittings is how many 90 an 45 degree fittings you are using
if there is it would reduce the pressure

i still think its hot, for my CF 7970 i can get 50C running uniengine with fans at 500rpm, idle is around 32C with 30% oc. Perhaps you need more fans and rad.
At one time i did stock rasa pump and a 655 running in series, like backup pump plus higher pressure too. Works really well. In case the rasa pump fails the 655 is there.

anyway just buy the mcp355 and try, i hear the rasa pump can fail under a year perhaps being overstress.

i read
he is using 1 pc of gtx580 while i am using 2 pcs of 7970
so it cant be that far off

for mine the furmark was around 48C for 1 card

did not read on how to do 2 cards to work with furmark

looks good, that is our i am mounting my 2pcs of 480 rads
i guess you will be changing to a full length chassis soon

Aren't the fans noisy i see you hook them up to the PSU without a fan controller
Looks like a feser rad

I think ek is mid to high fpi
It would benefit from delta just the noise level is high

Based on theory the rs360 should be better as it has more surface to radiate the heat as its thermal capacity is higher.
Rs has high fpi so with most fans working around 1500 rpm it would be better

More surface area for the fans to blow thru. Normally slim rads needs to use fans that are high rpm. Slim rads have more fpi so the fans needs to be faster to generate high static pressure

Yes because the higher fpi increases air resistance which needs to be overcome with static pressure

Looks good, i think the bitspower fittings looks nicer for the 90 degrees

It's 2 pieces of mcp355 with xspc top. Can see on the left and you have mention you will be using.
Seems to be fitting for a test bench.

I use a dual mcp35x to make waterfall in the loop

actually you should borrow a lamptron insert in the temp sensor at your mosfet heatsinks
mine in between the fins shows 48C during prime 4.9Ghz. using a haf912 chassis
so the mosfets should be about 55-58C then.
this was the hottest mosfet bridge

MB heatsink not much use to watercooling unless you chassis has not enough air flow

but watercool looks good like pro

yes that too, i think if you are going to cool the mother board may have to use the d-plug. Looks nicer than tubing.
I think the cooling for motherboard and ram is the least return in investment
unlike gpu and cpu where the heat level is much higher

Sometimes in review say this product better like CPU block
Ray storm being better than rasa for instance but when you try both products end up the same temp
So it's good to discuss the findings.

So ask away would be beneficial anyway

normally for any heatsink design the formula is
Temperature=Ambient Temp + (Watt * Heatsink Resistance)

MOst the of the rads are like 0.08 C/W means for every 100 Watt of heat the temp goes up by 8C . Add it to the ambient temp and that is the device temp. Too see the rad resistance some of the review sites do post it
To be below room temp need to use peltier cooling system
