What temps to expect

johnrs · 25 Jan 2007 at 14:49

I have recently brought a Thermaltake CL-W0075 Big Water 735 Liquid Cooling Kit for my CPU.. Might not be the best in the world but I am happy with it..

My CPU is a Intel Core 2 DUO E6300. My question is what would I expect to see temps in both idea and load..

Thanks

That's an impossible question to answer unfortunately. You say you are happy with it, so why ask?

johnrs · 25 Jan 2007 at 15:22

I mean I am happy with the setup.. Block, pump rad etc, the look of it and stuff

Temps I am getting at the moment are about 50deg under load. Its seems a little high to me (might be expecting too much). I have got some better thermal paste and will reseat the block this weekend to see if that makes a difference.

50C under load sounds quite good actually. My Alphacool/EK passive system does 65 under load and I'm quite happy at that because of the lack of any noise at all.

Is it overclocked?

Bit warmer than my Freezer 7 pro with a 120mm fan (running at 850ish rpm) at 2.8ghz. Of course it depends on the fan speed you're using, ambient temp, how well it is fitted, is the IHS flat? etc.

not at the moment its not..

Thats good to know that. I know that you cannot say for sure what temps to expect but I wanted to get an idea if that was good or bad. Guess I should have posted a little more info to start with.

Thanks for your reply

Shouldnt go over 60 as a thumb rule for c2d if you wanna keep you cpu for any length of time.

And idleing should be around the 35-40 mark ideally!

I have some Akasa Thermal Compound Pro Grade 460 so I will reseat the block over the weekend in use this instead

Thanks for the info guys

Hi,

That's very different to what I've been told before. If you could, could you give your reasons for saying that? Preferably with some sort of Intel specification or something?

What sort of reduction in life expectancy would you predict on an E6600 running 24/7 @68C?

Trusty · 28 Jan 2007 at 04:06

A friend of mine said that as a thumbrule but he's no expert. He knows his stuff but no pro or anything. Looking around tho, it seems people are running these over 60 with no adverse effects.

60.4 Degrees is the tCase temperature (measured with a probe on the outside of the IHS. 85 degrees is the maximum junction temperature, so if your using TAT, or Coretemp to measure the temperatures then anything < 85 is fine really, although I'd recommend keeping it below 70. Mine sits around 63degrees at full load, and I'm not at all concerned about it failing early because of this, because its well within intels spec.

For some reason the E4300, and E6300 have a tCase that is 1 degree higher than the higher end models.

Why? If 85C is the maximum, why not run it a the maximum? Isn't that a bit like saying my car has a redline to protect the engine at 6500RPM (just like the Intel Thermal Management Throttling system) but I only ever drive it at 5000 RPM because that's safer? It's not safer, it's just quieter (in both cases

)

I don't think that analogy quite holds water. If you throttled two identical car engines, one at 6500RPM all the time and the other at 5000RPM, the first one almost certainly would fail earlier.

Well, the chips warrenty is valid and the processor should last a good long time, even if it has temperature spikes close to its 'red line' at 85 degrees, it even has thermal throttling to give an added layer of protection.

However when overclocking higher temperatures can lead to stability problems, which while not actually damaging to the processor, can crash windows/applications or even just add subtle errors to the cpu's results.

By keeping the temps under 70, everything is just 'better' in my opinion. Then you have the issue of noise as you mentioned yourself. Even at 70 any speed controlled CPU fan will be going like a bat out of hell. I perfer to try and build quiet PC's. My own Idle's at 35degrees, under normal 'high' load around 50degrees, and under full '100% both cores' load around 63. The fan noise is still fine even at 63.

Well argued post

Yes, I couldn't disagree with anything you've said there. Strangely enough my system runs hot because I want it silent. I have passive water cooling which is almost completely free of moving parts and you really do have to touch the system to feel it vibrate so you know it's on. Because I'm at the absolute limit of the system's capacity, I'm having to accept high temperatures in exchange for silence - same problem, different solution.
