Cool Q6600 L725A903 - Swiftech G4 Storm H20 vs Thermalright Ultra 120 Extreme AIR

Trying my Q6600 L725A903 G0 cpu for the first time on Asus Blitz Formula. It's also first time I've tried air cooling on this Q6600 L725A903.

Full batch details:

Q6600 SLACR
FPO/Batch: L725A903
Version: E10342-001
Pack Date: 07/31/07


To cool Q6600 L725A903 G0 cpu, I decided on using my Thermalright Ultra 120 Extreme with 120x38mm Panaflo 103cfm fan and Artic Cooling's MX-2 thermal paste.

Surprisingly, with Thermalright Ultra 120 Extreme air cooling, I'm getting similar cpu load delta temps (coretemp) as with my Swiftech G4 Storm water cooling setup - air cooling approximately 1.4C delta cpu load temps behind and 0.4C warmer in terms of cpu idle temps above room ambient. But air cooled setup is running Prime95 torture test at less vcore even when room ambients on air are warmer!

@3600Mhz at 1.432v load on Asus Blitz Extreme - Swiftech G4 Storm H20
CPU load to room delta = 57C - 24.5C = 32.5C Delta


vs

@3600Mhz at 1.408v load on Asus Blitz Formula - Thermalright Ultra 120 Extreme Air
CPU load to room delta = 62C - 28.1C = 33.9C Delta


System
  • Intel Core 2 Quad Q6600 L725A903 7/31/07 pack date G0
  • Thermalright Ultra 120 Extreme + 120x38mm Panaflo 103 cfm fan + MX-2 TIM
  • Asus Blitz Formula 1101 bios
  • 128MB Gainward FX5200 PCI
  • 2x1GB Crucial Ballistix Tracer PC2-8500
  • Memory cooling = 120x25mm Spire 96cfm fan on rheobus @100% fan speed.
  • 80GB Hitachi 7K80 SATAII
  • Pioneer DVR-08 Burner
  • Sony FDD
  • 620W Corsair HX620 PSU
  • WinXP Pro SP2

room temp = ~28.1C

Re: Q6600 L725A903 - Swiftech G4 Storm H20 vs Thermalright Ultra 120 Extreme AIR

Compared to on Blitz Extreme with Swiftech G4 Storm water cooling!

System:
  • Intel Core 2 Quad Q6600 L725A903 7/31/07 pack date G0
  • CPU cooling = Swiftech G4 Storm/Thermochill 120.3/MCP655 (with AS5 TIM)
  • NB chipset cooling = Radiical Chipset Block/Corsair Cool single 120mm fan Rad/MCP350
  • Asus Blitz Extreme 0804 bios
  • 128MB Gainward FX5200 PCI
  • 2x1GB OCZ PC3-14400 Platinum - DDR3-1800 rated at 8-8-8-27 at 1.9v
  • 500GB Seagate 7200.10 SATA on SATA1 Port
  • LiteOn 165H DVD Burner
  • Sony FDD
  • 1KW OCZ ProXStream
  • WinXP Pro SP2

room temp = ~24.5C

Could it be Swiftech G4 Storm waterblock is clogged or just not quad core optimised ? Or could using MX-2 thermal paste on Thermalright Ultra 120 Extreme giving that extra bit of assistance where required ?

Or that Asus Blitz Formula clocks Q6600 L725A903 quad core better than Asus Blitz Extreme ? From my E6850 L723A347 tests, the Asus Blitz Formula does clock better than Asus Blitz Extreme - difference in max FSB was 485FSB on Blitz Extreme vs 530FSB on Blitz Formula!

Or it could just be the fact that it's long overdue for my Swiftech G4 Storm to be cleaned and the water cooling loop redone

Whatever the reason, this Q6600 L725A903 managed to pass wPrime 32M & 1024M tests @4181Mhz on Swiftech G4 Storm water, so wonder how it fairs on air cooling ? We shall see

Re: Q6600 L725A903 - Swiftech G4 Storm H20 vs Thermalright Ultra 120 Extreme AIR

@4185Mhz at 1.648-1.656v idle
Went for broke to see if i can break my max cpuz validation/wprime 32M that I achieved on Swiftech G4 Storm water and nearly got there - 4mhz better on CPUZ Validation but 4mhz behind on wPrime 32M max clocks

Q6600 L725A903


@4176Mhz at 1.648-1.656v idle



Couldn't submit to wprime/hwbot automatically some problems at wprime.net ?

Q6600 L725A903 Max FSB Tests

Seems Asus Blitz Formula of mine has slightly better FSB for Q6600 L725A903 than Asus Blitz Extreme. On Blitz Formula, the Q6600 L725A903 could easily hit 490FSB before needing CPU PLL voltage adjustments compared with Blitz Extreme 485FSB mark. Also max bootable FSB was 505FSB vs 500FSB in favour for Blitz Formula.

But for any form of stability i.e. Super Pi 32M or Quad 16M Systool PI test, it was pretty close 495FSB for Blitz Formula on air versus 493FSB for Blitz Extreme on H20 cooling.

George

Those temps seem about right to me for the watercooling. The mx-2 is good stuff though. I changed out the swiftech stuff on my 8800 for mx-2 and got a drop of about 4c.

With a different block(maybe bowed) and the mx-2 at 24c ambient I reckon you might be able to drop the idle temps down to the 25-27c mark. I'm going by memory of how mine performed. I've now got the 8800 in my loop so can't really make a comparison.

It's certainly testament to the Thermalright though

Cheers
