Asus Blitz Extreme alternate NB/SB/Crosslinx cooling - underneath the heatpipes

[eva2000]

Ever wondered what's under all those heatpipe heatsinks on the Asus Blitz Extreme (DDR3) motherboard ?

Radiical Chipset Waterblock
I thought why not try water cooling the Northbridge ? From reviews water cooling on the Fusion Block System didn't improve overclocks at all only temps. So thought doing away with Fusion Block system and instead use my Radiical Chipset waterblock in a Corsair Cool single 120mm radiator/fan with MCP350 pump in a 3/8" tubed loop.

Stock motherboard cooling with Swiftech G4 Storm installed



Southbridge, Crosslinx core, Northbridge P35 chipset core and mosfets.


A look at the state of the TIM appliacation on NB, SB, Crosslinx and mosfet heatpipe heatsink

• For Northbridge core used Radiical chipset water block with 3/8" barbs.
• For Southbridge core cooling used a heatsink off my old Asus P5W DH motherboard.
• For Crosslink core cooling used a heatsink off an Abit motherboard with Sekisui #5760 thermal tape - sawing off one side's retention piece.
• For mosfet cooling, reused some Microcool aluminium heatsinks with Sekisui #5760 thermal tape.
• I used some 3M Scotch Vinyl insulating tape over NB core components and also near dimm slot cloest to cpu socket as the Radiical chipset backplate is touching some pins coming out the back of the motherboard.

But NB temps dropped from 32-40C to 23-26C and SB temps dropped from 32-36C to 28-30C at similar voltages

Update: Actual figures

Well here's before and after at same 8x450FSB 1:2 900mhz 7-6-5-18 4-48-6-8-8 at same vFSB/NB/SB voltages of 1.34v/1.49v/1.05v respectively.

• Before = stock heatpipe heatsink NB/SB/Crosslinx/Mosfet with 120x25m Spire 96cfm fans cooling them
• After = Radiical Chipset water NB + P5W DH SB heatsink/Abit blue heatsink Crosslink/Microcool Aluminium heatsinks for Mosfet with 120x25m Spire 96cfm fans cooling them

Before

• MB = 24C Idle / 25C Load
• NB = 34C Idle / 37C Load
• SB = 32C Idle / 33C Load

After

• MB = 25C Idle / 25C Load
• NB = 27C Idle / 28C Load
• SB = 31C Idle / 31C Load
