MCP655, Powerful enough??? - Page 2

post #11 of 14
You probably had a bad mount the first time round. I can't see that an additional rad could drop water temps by the 10ºC you'd need to get a corresponding 10ºC drop in CPU temps.

Bah ... bad mount ... I dont believe it.

In next few weeks I´m gonna add one EX360 more and change CPU block to Raystorm. This time I´m expecting only 1 or 2 degrees drop.

Only way possible to get a 10c drop from adding rads is to change the fans, Re-seat the blocks due to bad contact, or sudden change in ambient temps.
Only successful thing you will gain out of adding more rads for something that's completely overkill is less noise.
RX360 + RX240, one D5 pump (+ XSPC Acrylic Dual 5.25” Reservoir for Laing D5), Swiftech Apogee XT - Prime Large 9 hours
3 x RX360, 2 x D5 pump (+ Koolance RP-452X2), Koolance CPU-370 - Prime Large 12 hours
Room temperature was about 24-25 degrees.

Considering you did change your block, I am still going to say you had a bad mount on your first block, And if you do enough research, You to will understand it's almost impossible to drop that much degrees through rads unless you do something drastic like chill the water or something..

Like I said before, The main reason to add a lot of radiator surface is to gain very very low noise levels at the same cooling level as a Single 240/360 or Double 240/360 Rad solution

I have a dual pump top for 2x 655's, also use 2 480 Fesers. I found a big drop in temp doubling the rads, just one used to get warm and even hot at times.
Though with 2 now the temps on the rads never get warm in the slightest.

The main reason though for the dual pump top is redundancy, same as the second rad. One pump fails and the other will go on, the fan controller fries and the sheer amount of rad will keep everything cool. I like to leave my PC on for long lengths and I'm not usually home when its running so it give me piece of mind, and I know I cant get any better performance so I;m not always wanting to upgrade.
