    Default Cooling advise needed

    Hi all,

    Just satbilized my system on 333FSB, and now going for 400, starting at 8x400 3.2GHz. Only increased vcore a notch to 1.072 under load (just for safety,) tRFC by 10 to 52 and tRD to 7. Prime95 is running for about 3 hours now, and I still need to do OCCT OCCT/LINPACK but things look pretty solid so far.

    My problem is my temps, 45C@Idle, up to 59C with prime small FFT, and go up 66C with LinX/IBT.
    System/Motherboard whatever it is, is 43-45C depend on ambiant temp which is 28-31 during summer.
    I am assuming temps will go even higher as I'll push it further, so I need to get better cooling.

    My first question, will it be able to lower my temps substationally?
    I have my eye on the Scythe Mugen 2 which I can have for $66, or Thermalright Ultra-120 eXtreme RT 775 for $89, or the Thermalright
    Ultra-120 eXtreme 775 with Silverstone 120 Case Fan FM121 for $100.
    I understand the FM121 is a PWM fan evem though it doesn't specified on it's page.

    I have few concerns, my case is the second cheapest tower I could find (seller said the cheapest has too many problems,) So I need to see they fit in.
    The Mugen weight aomewhat less, but I can already see I am not going to be able to use DIMM slot 1 if I intend to use my G.Skill PI DIMMs (the same it is now with my current CNPS8700.)
    On the other hand, the Ultra-120 is longer and I might have a problem if I plan to add Northbridge cooler.
    I also had my eye on the Coolink ChipChilla, but do I need it? (currently the CNPS8700 is blowing down which probably help cooling the NB)

    I favore the Mugen 2 because, a. it's cheap and b. it gets good reviews, came second in this one.

    Any comments / suggestions, in favore or against will be apreciated.

    Thank you in advance,

    Chike

    Either of those HSF's would be good. Go with which ever fits your budget. With either, I wouldn't expect your idle temps to be much lower than 38-39c in a 30c room. It should decrease load temps though.

    IMO your P43 won't get hot enough to need an active heatsink. I'd save your cash, the stock cooling is fine.

    I don't know if your from the USA but these are great cheap case fans and could bet used on a heat sink I bet. I would consider using a fan controller with them though.

    Newegg.com - COOLER MASTER R4-L2S-122B-GP 120mm 4 BLUE LED LED Case Fan - Case Fans

    Also the Cooler Master V8 is a good choice for a HS. Could even use the above fan in place of the stock fan it shipps with.

    Other wise what you listed I am sure will work well for you.

    Thanks, I like saving money :-)
    It was very hoy yo touch at stock everything and I have no knowledge about it, so I thought I'd ask.

    I have a square and a circle openings in the left side of the case made of small holes, the circle has a sleeve that I'd have to take off that goes just a few cm above the HS. Maybe I'll put a low CFM fintake fan there.

    Since I have those openings would it be more resonable to add a front exhust fan or should it be intake? (not even sure I can install one there)

    Definitely best to keep the airflow in a distinct direction. Use fans set to intake on the front and side and extraction on the top and rear. Usually a slight bias toward output (more sucked out than sucked in) can aid cooling.

    No I'm from Israel.
    The store I plan to to order from does have Cooler Master fans, just not the same model, I thing I'll get the Long Life Fan 120mm as a standbye replecement to my 93CFM noisy case fun that already started making weird noyses. They also have the HS, a little more pricey than the Mugen but smaller dimentions so I'll look it up.

    So a 2x33CFM iside/front ntakes and 70CFM rare exhust would do ok?

    Thank you both for the replies.

    HS and fans arrived but I can't seem to find high-purity isopropyl alcohol here.
    They had Akasa AK-TC but I am not going to pay $25 for a 125ml bottle I am going to use once in a lifetime.
    Would a 90% aceton be enough? if not what other options are there?

    Best place to go for good purity alcohol is your local chemist. I had to answer a fair few questions when I first went in (due to implications in drug use, injecting stuff etc). Once I explained what it was for, the chemist was happy I wasn't a smack head and let me have some. I bought a bottle with an eye dropper in it, and he filled it up for me. I think the bottle is 60ml, and he charged a couple of pounds I think. The stuff lasts forever.

    Akasa TIM clean is good to. Smells like citrus peel.

    Been to 2 pharmesies already and they didn't have it, one said she could order a liter bottle but did not know it's purity, there another one that was closed, I'll check it again but odds they'll have it are slim.

    There's one I found online, but abroad, that may be a 2 weeks delay if it ever arrive.

    Oh one more question, I bought those MOS-C1 mosfet heat sinks but I have no clue how a mosfet looks like, what do I look for?

    The MOSFETs are the small (around 4mmx5mm) flat chips lying flat to the board, next to the chokes. The chokes are those larger square pieces that stand nearly a centimetre tall.

    I've attached a pic of the UD3 as it has no FET coolers, so they're visible.

    Edit*** The white squared off chips are also MOSFETS. I must have switched colours by mistake.
