Core i7 2700k + Thermalright HR-02 Macho - Not Cooling Correctly?

post #1 of 9
Thread Starter 
Hi,

I've got a Core i7 2700k with a Thermalright HR-02 Macho in a Fractal Design Define R3 case. The motherboard is an ASUS P8Z77-V and the OS is Windows 7 Ultimate x64.

I previously overclocked the machine, but right now (I think) that's been removed.

I'm using the machine to run some simulations, and when I've got 2 processes at 100% (so 2 threads on 1 core of the 2700k), ASUS's AI Suite II software says the CPU is at ~78C. When I look at SpeedFan, it says they're between 90 & 95C! This obviously can't be good for the machine, so I was hoping someone could help me out.

I've got an album of BIOS screenshots here, and this is what the inside of my case looks like. There's the big fan on the right side of the Thermalright cooler, and then a case fan to the left. The graphics card's 3rd party cooler also has 2 fans, but that's actually not in the machine right now due to another issue.

How do I solve this problem? I don't have much past experience with overclocking/cooling.

Thanks!

You have the CPU fan backwards in that picture.

Can't say if that's your only problem, but that's where I'd start.

When you say backwards, do you mean I need to move it to the left side of the heatsink, or that I need to flip it so that it faces the opposite direction?

As he said. See on your pic: there are arrows printed on the fan that indicate the right sense. thumb.gif

Just flip it.

The arrows on the fan indicate direction of rotation and direction of air flow, which should also be blatantly obvious from the curve of the fan blades.

You want the fan to blow air through the heatsink, and out the exhaust fan at the back of the case.

OK, I flipped the fan over, but it doesn't seem to have made much of a difference (AI Suite II now says 67, while the SpeedFan temps are between 80 & 90C). Any other suggestions? Just to be safe, I went into the BIOS and set it to the "optimized defaults".

Can't suggest much else besides reseating it. How did you apply the thermal paste ?

Open side of fan is intake. Motor mount side is exhaust. Never seen on that was different.

Most common ID.10.T error is fan running wrong direction. Second is forgetting to remove protective plastic from heatsink on bottom of cooler. biggrin.gif No I haven't done either one, but I have done far worse.... Like being head mechainic in race shop and assembling an engine with no crankshaft oil seal installed. mad.gif Didn't mind the oil puddle when we started engine, but the weeks... months... years of ribbing is never ending. rolleyes.gif

I suggest re-seating. Rub the paste that is on cooler base when you remove it into base like you would polishing a car or boat, then wipe off with lint free cloth.. Coffee filter is perfect. Paper towel is okay. Clean CPU and apply TIM.

I just followed whatever directions came with it. It's very possible I could have done it incorrectly though.

OK, it sounds like this is the most likely problem, so I'll try reseating it. I'll also check if the protective plastic has been removed.

I need to buy new thermal paste then, right? What brand should I buy?

Also, what temperatures should I expect to see when the CPU is under stress after all this has been done correctly?
