    It's 30 degrees in the office, core temps 48, cpu 42 at idle. That's on the lower overclock of 4.1GHz rather than 4.2GHz.

    I've got Arctic Silver 5 from the local service town 30km away, anything else would be an internet order.

    Have reinstalled twice with washer, and so far it seems to be running no cooler than before.

    What can you do, ambiant temperature effects cpu temperature liniary. I am still waiting for cooler weather to try higher OC.

    Would 4.1GHz be the limit for a 24/7 summer overclock then? :-)

    At 4.1 gets hot but doesnt fail linX and Prime
    At 4.2 gets hot and does fail linX and Prime

    Your temperatures would be quite good with your high overclock if the ambient temperature was about 22 (C). Your computer case could be part of the problem if there isn't sufficient airflow through the case from the case fans.

    I'm not familiar with water cooling setups and don't know how much more effective it would be with your nearly 30 (C) summer temperatures.
    **edit** I just noticed, you and I have the same computer case, the CoolerMaster RC-690. Are you using dual fans on the side and top case?
    Your pet on the top of the case is clearly obstructing air flow :)

    Just as they will be with lower temperatures, I believe, with a high level of certainty.
    The laws of physics don't change, the water block and radiator efficiency is a constant, same is the water efficiency, unless they change form.

    The pet was a gift, spoofing my surname, and was only there for the photo shoot I assure.

    Top fans? They would need to be thin to fit my cm690. (rc ?) 25mm too thick for space.

    I've got the lower side fan blowing in - drops system temp noticeably.
    Upper side fan mounted outside sucking out. No room inside as Thermalright 120 in the way. Base fan sucking in through filter. They are all Coolermaster 43cfm fans.
    There is a 40mm fan attached to the side of the NB with carburettor return springs.

    Rear fan blowing out. Five case fans.

    There are 2 x 120mm Noctua 54 cfm push/pull on the Thermalright 120, held by springs. Curse the standard clips!.

    30C? No, that's Spring. Summer will be 40C. Sub tropical where I live. We copped duststorms from the west this week. Covered the top half of the country nearly, but only made it 1200k out to sea before rain stopped it going further. Red dust in everything.

    I'm using four 1000 rpm Aerocool 140mm fans for the top and side case. They're 20mm thick and each fan comes with a 140 to 120mm (12mm thick) adapter. They are a bit pricey at $14 - $20 (USD) and use common sleeve bearings. Pretty good fans but for the same price, Noctua or Scythe fans are better.

    Using two of these fans might help somewhat, but I don't think that the improvement would be better than 1 or 2 degrees at best. I haven't tried the positive case air flow yet with both of the top fans pushing air into the case.

    You might be able to improve your cooling with better cable management so that airflow won't be as restricted. I've been able to route most of the psu cables behind the mobo back panel for less air flow resistance. It definitely allows the bottom fan's air flow to be less restricted.

    **edit** I saw the red dust on the TV news, it looked like the whole sky was on fire.

    LOL!!
    After my brain fogged over looking at the math involved, I'd rather put a few chunks of dry ice in my computer case and call it good!!

    I've been looking at AnandTech - Intel 45nm OC Result Thread (Wolfdale E8400/E8500/E3110) and I am at the zone where the x48 loses it, and the EP45 can go one more notch, as they said on one forum.

    External side fan seems to have no effect on displayed temps. I've thought of getting 140mm case fans, but probably at point where small gains cost. Only one shop in Oz had those fans and currently sold out. A search for 140 x 20 and 120 x 20 fans in Aus yielded zilch.

    Would it be realistic to say, that for a 24/7 overclock, using liquid cooling with quality components, I'd be looking at around 4.4 - 4.5GHz? Is that right? If it is the cost/benefit ratio is cause 4 pause.

    All those cables you can see at the bottom are going into the sidepanel thru the hole provided. The ones left out in the case are the problem ones.

    I read the Newton link, Chike. Brutally true.

    Dry ice will do you good, beware of condensation though, there's a formula for that too

    The math is not important, the simple principle is that to achive the same rate of heat loss, the temperature difference between two materials remain the same.
    The air temperature rise, so does the coolant, the coolant temperature rise so does the CPU, with the difference of temperatures between them rrmains the same.
