    Alright, firstly, I strongly believe in helping people help me, so if you guys have any questions for me or need more information please don't hesitate. I would say my Tech level is mediocre, and my experience with actual nuts and bolts hardware is fairly low compared to most. I've installed video cards and RAM, and aside from cleaning out my machine regularly that's about all the experience I have in terms of what goes on inside my machine. Now, onto the issue.

    Specs
    i5 760 @ 2.80ghz (No OC)
    4 gigs of DDR3
    1 TB HD
    GTX 560 Ti (No OC)
    700 watt XION PSU (Crappy I know)
    Liquid cooled
    1 Front intake, side case fan, rear exhaust fan

    I bought this system from iBuyPower (Maybe a bad decision?) a little over two years ago, so it's got some age to it. The only thing I upgraded in it was the video card a few months ago, which went well without a hitch. Up until now I've never had any problems with the system as far as temps go, it's always ran fairly cool as long as I keep it cleaned out. About a week ago I started to hear a low rattling type sound that's been there since. As soon as I turn it on the sound is there, and under load the sound becomes faster and louder. It's not high pitched or anything, just a low grating almost similar to how an HD sounds while working only much louder.

    I removed the case with the power on and listened in, and it sounds like it's coming from the heatsink that covers the CPU (If that's what it is?). It definitely isn't any of the fans, as they're squeeky clean and the noise just doesn't originate from them. So I'm wondering if combined with the noise and the high temps I get under load could it be my liquid cooling beginning to fail? I don't really know much at all about liquid cooling, but I did go ahead and order some Arctic Silver CMQ2-2.7G Céramique 2 Tri-Linear Ceramic Thermal Compound from Newegg due to the low burn in period. Anyway, some pics comin' at'cha.

    Inside of my case. That liquid cooling setup confuses the hell out of me.

    Questions

    1. How could my idle temps be so low, yet my load temps be so high?
    2. Should I worry if the cores sometimes show different temps?
    3. In SpeedFan, do I not actually have a fan spinning or is that a bug?
    4. I heard about CPU throttling at dangerous temps, can I still damage or fry my CPU if it's at 90c for too long?
    5. Aside from reapplying thermal compound (Which I'm set to do in a few days), what else can I do in the interim?

    Thank you muchly for your time and if you need any more info please ask. I'm kinda' paranoid in using this thing right now, especially for gaming. I really hope when I get the ceramique it'll lower those load temps.

    What brand cooler is that? I see no name-plate on it so hope its not something home-made. Dont have any experience with those type coolers anyway, but I wonder if the pump in it is malfunctioning and the noise may be from that.

    If you have the stock aircooler I would put that back on because it sounds like the water pump died on you.

    Yeah .. I'm beginning to suspect it's the cooler/pump as well myself. Apologies for the late reply; I haven't even had the thing turned on much at all today. It seems as though the CPU isn't being cooled at all. Idle temps are around 50-60c now, and even one core being at 50% load will put temps up to 80-90c.

    That is not good at all. I think the liquid cooling has completely failed and is fubar now. I have no idea what brand the cooling system is as it came prebuilt when I ordered it, but the good thing is I have a backup in an older PC I'm going to switch out later today.

    Question: From looking at the pic of my open case, can you guys tell me if I'll need to take my mobo out to remove the liquid cooling system? I'm really hoping I don't .. Those four screws you see are a pain, and I hope there isn't any washers or other screws behind the mobo keeping them in.

    Very much appreciate the replies.

    Take off the other door panel and have a look. Many cases have cut-outs behind the mobo to allow easy access to attach/remove the coolers retaining brackets or nuts holding the screws.
