Evoluzione scythe ninja

spcr_logo

Spcr(silent pc review) ha rilasciato in questi giorni una curiosa comparazione.
Loggetto preso in esame,come si può intuire dal titolo,è lo scythe ninja uscito sul mercato qualche hanno fa con la sua prima versione.

 

In questa comparativa spcr non ha fatto nient'altro che prendere le 3 versioni dello ''scythe ninja'' e metterle a confronto.
I risultati sono alquanto bizzarri.
Metodologia di test

 

Componentistica usata:

  • Intel Pentium D 950 Presler core. TDP of 130W; under our test load, it measures 78W including efficiency losses in the VRMs.
  • ASUS P5LD2-VM motherboard. A basic microATX board with integrated graphics and plenty of room around the CPU socket.
  • Samsung MP0402H 40GB 2.5" notebook drive
  • 1 GB stick of Corsair XMS2 DDR2 memory.
  • FSP Zen 300W fanless power supply.
  • Arctic Silver Lumière: Special fast-curing thermal interface material, designed specifically for for test labs.

Software utilizzato:

  • SpeedFan 4.31, used to monitor the on-chip thermal sensor. This sensor is not calibrated, so results are not universally applicable; however,
  • CPUBurn, used to stress the CPU heavily, generating more heat than most real applications. Two instances are used to ensure that both cores are stressed.
  • Throttlewatch 2.01, used to monitor the throttling feature of the CPU to determine when overheating occurs.

Software per lo stress termico usato:
-
CPUBurn

Temperatura ambiente (tamb):
21°

Rumore ambiente al momento dei test:
17dba

Commento spcr:

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
Conclusion #2: The differences between the three Ninjas are most likely caused by the variances in tension or pressure applied between the heatsink base and the CPU by each mounting clip. There seems little doubt that the original Ninja's mounting setup applies the highest pressure. This might actually be felt during installation, although we have no way of knowing for sure, as measuring the pressure when the heatsink is engaged would be quite a challenge. The CU's mounting system seems pretty close, but the small size of the tabbed hooks is not reassuring, and it cannot provide as much pressure; the thermal results speak for themselves. The pushpins of the 775 socket mounting for the current standard Ninja are quite poor in comparison. The move by many SPCR forum members to use Thermalright's LGA775 spring-loaded bolt-thru kit is an excellent way to improve the mounting setup of the Ninja with Intel CPUs. Surely, the tighter, more secure installation would improve cooling by at least a few degrees.

Spcr inoltre afferma che le prestazioni del ninja sono peggiorate dal sistema di aggancio di esso al socket.
Utilizzando infatti un sistema di ritenzione simile a quello pubblicato questa settimana( sistema di ritenzione secondario ) si ha un guadagno prestazionale di ben 4° nelle medesime condizioni.
