watercooling question

Hey guys, i have a q6600 g0 overclocked to 3.6GHz with a lapped thermalright ultra 120 extreme. its idling at around 35c and at full load it gets to about 65c. im pretty sure these are safe temperatures but i would like them to be lower (55c would make me happy). so my question is, how much of a temp. difference at load could i get with a good cpu only watercooling system? this was my first build and im sort of a newb to all of this so i dont know that much about watercooling.

thanks
 
assuming your case ambient temp is around 30c, with top of the line watercooling your idle temps will drop to about 30c, and your load temps will drop to about 50c. it also depends where you put your radiator, if inside or outside the case. I am assuming you are going to put it inside, so your ambient temp is 30c. if you place it outside, and your room temp is 25c, then your cpu temps are obviously going to be lower.

what makes the difference with water cooling is your core temperatures. the delta between IHS and core temperature is drastically reduced with water cooling. if you idle around 30c, you can expect your 4 cores to be around 35c, and if you load at 50c you can expect them to be below 60c. with air cooling this doesn't happen. the delta is usually greater than 10c.

if your cpu is running at 65c while doing prime95 small FFT, it means that under normal load it probably runs around 50-55c. if that is the case, I strongly discourage watercooling, because its very expensive, and its not the easiest to setup. if that is not the case, then you may want to look into watercooling, at which point I pass the ball to aigomorla and I recommend you send him a PM.



 
is the case ambient temp the system temp? and if not where can i find my ambient temps? im sort of confused about which temps are which. is the cpu temp reading my IHS reading? my cpu reading is only about 2 degrees higher than my core's reading. now im really confused lol
 
yes, the case temp is reported as System temp or Motherboard temp by most programs. Its just a sensor on the motherboard that measures the air temperature. this is NOT the northbridge temperature. the northbridge temperature (which is usually only reported in the bios) is much higher.

the IHS temperature is the cpu temperature reported by most programs. the core temperature will NEVER be lower than the core temperatures. on air cooling, the core temperatures are roughly 10-15c hotter on a quad, and 5-10c hotter on a dual. if your core temperature are lower than your IHS temperature, you are probably experiencing the "-15c" core temp bug, which means that your core temperature are actually running 15c hotter than what it reports. I have a feeling you are going to pull your hair out now that you realized your core temperatures are actually 15c higher under load. make sure you keep core temperatures below 71c for a G0 revision CPU.

uhhh... if your a newbie at overclocking. You should be aiming for something lower then 3.6ghz.

I got b1tch slapped by jag for comparing a 3.6ghz quadcore in terms of overclocking to a E6600 dualcore.

After tons of failed hardware, the board gets stressed hardcore at 400fsb, i reailized i should just keep my mouth shut on recomending any overclock.

What has failed?

1 ram stick of my crucial tracers.
2 EVGA 680i boards.
1 PSU even down the drain.

:T

3.6ghz is not a walk in the park. You'll find this out quickly when you load her on full load.
 
Unless youre severely overvolting, or get cheap parts.

30C idle 50C load.

Apogee block
Swiftech MCP355 Pump
Swiftech triple 120mm radiator
Reservoir of choice (doesnt really matter)

All of those failures could be related to a dieing PSU.

Yea, but the PSU was the first to go. 😛

And it was a seasonic M12 600. from way back ago.

My best psu right now is my antec Quattro 850W. I have 2 of them pushing 2 quads hardcore. One at 3.73 and the other at 4.05 ghz.

Absolutely love these psu's.
 
ive already added 15c to all my core temps bc when i first dled speedfan 19c seemed impossible lol....so yea i think my core temps are right but im still not too sure. are there any programs that will accurately report my temps other than speedfan?
anyways right now in speedfan im getting 33c for the cpu/ihs temp, core 0 39c, core1 40c, core 2 38c, core 3 40c...does that sound right?

i should probably mention that during prime 95 my cpu temps seem to run a couple degrees hotter than my core temps until about 20 minutes into it when my cores stabilize at 65 and my cpu stablizes at 62.....is that anything i should worry about? again i added 15 degrees to the core readings in speedfan

btw thanks for all the info...these forums are great. ive spent 5 hours reading about this stuff and you all answer my questions in less than 30 seconds lol
 
yes those temps do seem right. that damn ultra-120 extreme is impressive. its practically as good as water cooling, except that water cooling will handle the load punch a lot better. but still darn impressive...

ignore unlabelled temps in speedfan.

I disagree a bit.

Fuzion or Apogee GTX (is that what you meant?)
MCP655 Pump
swiftech or thermochill triple 120mm rad
whatever res



@ aigomorla

isn't it funny how the same guy that bitch slapped you, disapproving that a quad needs to be clocked at 3.6 ghz to perform well, ends up having a quad clocked at 3.6 ghz? :laugh:

haha, what goes around comes around!

its all thanks to G0 though. G0 has raised the bar for quads to 3.6 ghz for safe and stable 24/7 operation. B3 was stuck at 3.2 ghz. now hopefully Yorkfield will raise it to 4 ghz. it seems like you are always a step ahead of the generation terry. when everybody else is "safely" running at 3.2, you are juicing 3.6, and when were all running 3.6, you are squeezing 4.0. stunning really 😛

take care boys time to go for some ice cream 🙂
 
What kind of casefans you running? The coretemp you mention isn't cpu/ihs, I think, it's the temperature in your case. Must say it's a bit high, which could mean that you don't have a lot of airflow going on in your case.
 
my system temps seem to be a bit high. right now its reading 54c but it doesnt seem to flucuate at all between load and idle. it might rise to a max of 57c. i should probably add that it doesnt seem that hot in the case and nothing is even hot to the touch...my ballistix was even kind of chilly. i have a gigabyte aurora 570 case and the airflow in this thing isnt that great...but my temps seem to be in line with these... http://www.hardwarecanucks.com...a-570-case-review.html

i have added a fan to hard drive cage and a fan to the mesh side panel to increase airflow.
i have the 3 stock 1000rpm POS's and 3 scythe sflex f 1600rpms, 1 on the heatsink and 2 in the above positions.
that reminds me, does anyone know of any good blue led case fans that are quiet and push a lot of air? ive done some research but cant really find anything that stands out as the top of the line...

anandtech forums rule!!!
 
Antec tricool should come with a blue led, but aren't as quiet as sflex fans. They are mildly quiet at medium though and quiet enough at low, and do push a lot of air.

Of course i meant the apogee GTX 😛
The MCP655 is larger and king of noisy, not to mention the price is pretty high, not to the point where i wouldnt reccomend it, but for most applications its not neccesary.
I completely agree on the block, rad, and res.
