Q6600 B3 vs G0

[twistedheat]

For those that have owned both a B3 and G0, this question goes out to you. How much of a temperature drop did you see when changing from one to the other? This is based on same cooling and same clock speeds between the B3/G0 comparison (if you can remember).

I am looking to purchase a G0 but already have a B3. Main reason is that even at stock speeds (2.4ghz), using Arctic Freezer Pro 7 and Arctic Silver 5 (applied using the method on the website) and after several reseats, I'm still hitting 72ºC under prime 95 load. My case is an Antec P180B with all three fans installed so I'm pretty sure it is the CPU that is a wrong'un. It is leaving no headroom for overclocking.

 

[Diggsy]

I don't remember my exact drop but it was somewhere between 10 and 15c.

What I can tell you is that at 3ghz my system hits high 60's when Priming with the G0, whereas with the B3 it was high 70's.

Also, I have been able to limit the speed of the fan on the Arctic Cooler now. It never goes over 2100 RPM. With the B3 it very quickly (and loudly) hit 2500RPM.

Exactly what I wanted to hear!

OCuK, sign me up for a G0. Haha. Placing my order now.

It's well worth it IMHO unless you intend using custom water to cool the B3. Also, I managed to sell my B3 on the 'bay for the same amount I bought the G0 - Result!!

I've seen a lot of quads recently go for £130ish + p&p on the bay, so for a ~ £30 outlay I don't mind having the better quad. With the B3 I would have had to leave it at stock. With the G0 I'm certain I will be able to hit 3.1ghz easy given the lower temps and higher temperature threshold.

 

[The Asgard]

Went from a B3 to a G0. Lower temps, higher clocks at lower volts. Worth the money

 

[Biffa]

I'd say you drop about 10-12 degrees under 100% load with a mild overclock (say 3-3.2Ghz)

Doesn't it depends on when you got your B3?

Newer B3's are likely to be closer to G0 anyway, so unless you have an older B3 it might not be worth the upgrade. Although from having seen your temps, it sounds like you must have an earlier version

Haha, yep. Pack date on the box says 02/01/2007.

A better HSF might be a simpler, cheaper solution. The ACF7P is a good budget cooler but not really in the right league for an over-clocked quad. Any of the ~£30 HSFs would be much more appropriate. I've tried the Tuniq Tower, Thermalright Ultra-120 Extreme & Zalman CNPS 9700 and they all shift the heat very well.

I have a B3 quad with a Tuniq Tower. With a 1.4v V-core, it's @3.2 and the temps hit 70-71. The temps look quite high but the B3's don't throttle till 100deg, where as (afaik) the Go's throttle @85.
Your temps do look high for the settings you have though. Try lapping your cpu and cooler.

That's wrong, look at the specs on Intel's site. They list the B3 as having max tcase temp of 62.2c, whilst the G0 is 71c.

That would mean the G0 would have the higher tolerance to heat, not the B3.

i personally have great respect for freezer 7 pros, but id use something more for cooling a quad core
preferably a cooler that you can pick your own 120mm fan

tcase and Tjunction are two different matters. Both B3 and g0 have a 100C Tjunction if i remember correctly.

 

[DavidB]

yeh, upgrade the CPU cooler, then upgrade the actual CPU when the penryn's are released.

Agreed that whilst the Arctic Freezer Pro 7 isn't the best of coolers, it should easily keep a stock B3 quad down in temps. Therefore, my only conclusion is that the B3 is a wrong'un. No big deal though, sold it on the bay for £142 and I am paying £160 for the G0 so £18 is not a big outlay. The equivalent of 5 pints at a bar.

Agreed that the ACF7 is not that a brilliant of a cooler, my c2d @ 3.2 hits 63*c somes times using TAT @ 100% load both cores. Depending on ambient temps..

Edit: hehe hadnt realised someone else said that about the ACF7 sorry...

 

[TheOtherOption]

My B3 @ stock under load only hits about 60 odd with a Noctua 120 cooling it - and that's with a very dodgy first install - gotta re-seat it sometime soon as we musta put soooo many air pockets in there when applying it first time around :/

Your B3 could do with a good lapping.

My G0 at 3200Mhz was hitting a scorching 70°C 70°C 58°C 58°C there abouts on its cores in prime, cpu Ihs is a big factor, my G0 Ihs was convex i.e. bulging up in the center, after lapping it averaged out at 66ºC 66.3ºC 66.2ºC 66.3ºC for a 15 prime session at 3505Mhz with a Tuniq Tower on top.

Guilty Ihs

In a nut shell the B3 is hot but the G0 could be every bit as hot with a bad Ihs, luck of the draw.

 

[CyZMyAssBaby]

my B3 was very concave and resulted in high temps

My temps before lapping idle were 53,52,49,48. Under load using prime 72,70,58,58

After lapping using a artic pro7 the temps fell to 33,32,28,28
under load 43,42,38,38 using prime
