So, ive got a b3 @3.0Ghz With the coolermaster Gemini II Board and cpu cooler on it. I though that this cooler was a good one because of its size and ratings on many sites. But i have to say im not liking what im seeing through core temp.

I have the voltage @ stock and the FSB @ 333*9

here are some screenies. ive checked the contact of the cooler, im using 2 coolermaster 120 mm fans on the heatsink and i just cant seem to get the temps down at all.

Seems normal for a B3. Your loads (theoretical max loads) with that cooler will be like 60-65C maybe closer to 70C... Realtime loads might generate somewhere in the 55-60C range depending on usage and calculations needed.

You also have a pretty high VID to begin with, which you indicate why you are seeing this, there is still a debate on whether or not VID matters when OCing and final voltage/temp results, I believe this to be true as any chip I have ever owned has followed this theory.

Pardon the "Scrub"-ness of this question, but I am pretty amateur at this and occasionally run across a question I can't answer via google, wikipedia or some other sort of internet perusal....

"VID?" - A little help with this one? Trying to figure it's significance.

The only thing I can come up with is Voltage Identification Digital... but the description I dug up was pretty vague and had no other references or citations.

ChaosMinionX

Its the amount of voltage the chip was binned for in testing to run Intels reference specs of that chip. So at 266mhz FSB with a 9x multi on the chip it took 1.3250 volts to make it stable at that, its Voltage ID basically for that chip.

Its unproven whether or not it has any relevance to Overclocking or not, but it has some basis of truth.

Well when you say "that cooler" is this a "not so great one" I had read many reviews that it was an excellent cooler. But IMO well actually as a FACT i dont like what im seeing and if it means that it has to be replaced then it will be. I dont see how its such a dud when its HUGE! and 2 120 mm fans? does the heatpipes just not work?

Please suggest me another cooler for this roasting hot B3. Sub `$50

Heres is what i was considering

Freezer 7 PRO
Newegg.com - ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler - Retail

Scythe ninja
Newegg.com - Scythe SCNJ-1100P 120mm Sleeve CPU Cooler - Retail

Zero Therm
Newegg.com - ZEROtherm BTF90 92mm Silent UFO CPU Cooler - Retail

yep i think the same as ChaosMinionX. based on my Core 2 Duo processors B2/L2 if the room temperature is at or a little above 30C , then that Core temps of these processors would be a bit lower than that,
but the Core 2 Quad B3, which has more L2 cache, will be just about right on the Core temp of that processor.

and the CPU cooler unit is not just nearly the best yet for the processor overclocking needs.
try a different fans, MX-2, and see if it will help.

procupine14

yeah i don't think you are going to really see a huge drop below those temps by switching coolers

Not a one of those is going to handle a quadcore OC'd.

Get a Thermalright Ultra-120Extreme, you wont be disappointed.

ok, so what are the "normal" temps for a B3? reason i ask is because im getting the same temps @ 2.4 and overclocked to 3.0ghz

PangingJr

since your overclock is low and you have the CPU core at the stock voltage, try activating these CPU's features in BIOS, Enhanced Halt State (C1E), Enhanced Intel Speedstep Technology (EIST) and Intel Thermal Monitor 2. and see if this helps drop the CPU's multi, CPU core's voltage and the CPU temp itself to lower levels while the processor is in idle.

josh2thad

Well i think i've found my problem...
I have a 8800 GTS, and its heating up my entire case, i mean you should feel the heat rolling off this thing... and it goes righ up and over the heatsink

I have afan on the site sucking in cool air but im going to reverse it to suck the hot air off that card and see how that goes.

The GPU is idle at like 50C i tunred the fan on it up to 60% constant.

PangingJr

so you just found that out.
well the heat inside the computer case should be the first thing you need to eliminate when you are overclocking the system. don't you think?

josh2thad

Well i've not had the GTS in there that long. and with a 200 mm and and 4 120's thats the last thing i was thinking actually.

Lelisevis

I have a Q6600 B3 and a pair of 8800GTS in SLI don't talk to me about heat LMAO. I have the side panel off and aircon in the room and thats with a thermaltake armor.

josh2thad

Well i hate to have to remove the such a cool looking stock cooler on a ($300) ( A LOT of $ To me) haha. I cant even imagine SLI? I actually managed to get the temp down to 42Idle @3.2 With a few tweeks but im shooting for the 30's idle 40-low 50's load.

What kind of temps do you get Lelisevis? on your CPU? And GTS's?
hows the Ultima 90 or whatever its called?

PangingJr

change the CPU cooler to tower-style heatsink to help push out more heat and faster, and try using low RPM fans for intake air and use a more powerful case fans for rear exhaust fans. and if you prefer to lap heatsink, or both heatsink and CPU, i believe that will help quite a lot in lowing the CPU temps.

Lelisevis

Ultima 90i is amazing. Idle at 38-39 and load is mid 50's at 3ghz. Idle on the GTS cards are 50 give or take.

The only thing I would say in this regard is that while their results are probably pretty accurate, there's a few other things to consider, like PS location, and a few other elements.

The concept of convection comes into play heavily, as well as fan location, velocity, raw flow and the possibility of turbulence inside the case.

Few other factors are how well the case is sealed and the design of the case.

I'm no scientist, nor do I even have a degree of any sort, but these are the concepts that stand out to me.

Smaller fans at high CFM ratings will produce velocity. - You don't want velocity unless you're pushing outside the case.

What you want in the case is volumetric flow. That's why 120mm fans have become the norm as of late - High CFM, low RPM, Low Velocity.

Velocity ends up creating turbulence inside the case - which fan can overpower the other?

What you want is smooth intake and directional flow following convection to quick evacuation outside the case.

This is why I went with the Antec 900 in the first place. The 200mm fan at the top isn't there with the idea of being the primary exhaust fan - it's merely promoting convection in the right direction where the 120mm fan on the back evacuates most of the heat from the case - It's a very low rpm low cfm fan that pulls from a wide area.


The next is logical direction of fans - I've set up cases with a rear intake fan across a radiator and top exhaust (Right above the intake), and a front intake fan with a load of velocity and CFM to cool the SLI'd graphics card. - It was sectional. The Graphics cards (8600GTS's) had their own exhaust slots on the rear, and it works pretty well. The two 8600GTS's stay at around 58C loaded with stock coolers, the CPU (Athlon X2 64 6k+ stock clocks) rarely breaks 45C. (Antec P180 with Swiftech everything on the liquid cooling, Apogee GT water block - I would have gone with DD, but it was a combo deal the guy I built for preferred.) - Nothing lapped.


Currently, I have a Thermalright HR03+ cooling my 8800GTX wrapped around the card (rather than extending away from the card), and the 92mm fan on it, is pulling air through the HR03+ rather than pushing down into the back the card.

Were I to swap directions, and push air down onto the back of the card (through the HR03+) it would actually increase my temps, as I'm moving against natural convection and the pull of the 200mm fan and the V1 on the CPU. - Creating turbulence and vacuum at points in the case.

I suppose this is a "Duh" response for some folks.

Here's my case and flow directions, spare the 200mm on the top.

Edit: Changed to a link, Pic was too large.

The rear fan I have on mine could be eliminated, spare that it affects my temps in no way, and I have no other use for it.

Current Temps as I browse DH.net's forums (no other load spare Windows Media Player) 42c CPU, 27C System, 49C GPU, Per nV monitor.

There's one other thing I'd mention that didn't really fit into the context of Chaosminionx's post in the Hardware Forums regarding the TR 120 Extreme and the gaps it had. I would have posted it as a reply there, but it seemed a bit out of context to the whole of the discussion. This seems to be a bit more related to fan placement per the quoted text, but perhaps this post is as well. I dunno.

One breath can fill one of those plastic bags they put newspapers in because it's pulling air from elsewhere along with it - A Venturi effect.

Taping the push-through side of a Thermalright 120 Extreme would be wasted in this regard - you'll get more flow by leaving it un-covered. That's why thermalright designed like that. The exhaust side, I could see taping, however as you may not want ambient air in the case being pulled with the air exiting the heatsink.

Trivial, but it may make a slight difference.


There's my three beer'd post. I'll check it tomorrow to edit it for clarity and stupid beer'd up mistakes, but hopefully this helps someone.


At this point, I'm on a bit of an un-sober tangent so...
Back to my Stella.

Sorry if I was totally offbase on this. I'd be happy to delete if this is wasted forum space on an idea I was 100% clueless about.

Those temos are really nothing to worry about IMO... worry when you're idling over 55 - 60

josh2thad

i got it down to 38 Idle with a scythe ninja plus Rev b, i got a good deal on.
