This is cool

[BaldEagl]

I just installed an Arctic Cooling Freezer 7 Pro and dropped my CPU temps by 10C.  Now idling in the low 30's (32-33) and under 50C (47-48) at 100% extended CPU load in Prime95 at ~73F ambient.  Woohoo!

This is according to Real Temp which I notice reports temps ~3-6C lower than the Nvidia monitor (Nvidia 780i mobo).

I had to remove the side duct on my case to get it to fit.  I also installed an 80mm side intake fan after removing the duct but it was so annoying I removed it so this is with nothing in the side.

I guess I've been wrong all this time.  An aftermarket cooler is a worthy investment.

I remember reading a thread on tomshardware about where different programs read the system temps from explaing why your motherboard monitoring software reports different temps between itself, speedfan, etc etc.  Alas, I can't find it.

That's pretty cool.  I've always been leery of active cooling, due to the risk of condensation.  That is an active cooling system, right?  

Anyways, I'm lazy so I just use a Koolance Exos for my watercooling setup, been happy with it, thought about upgrading to one of the newer Exos' with more speeds and 120mm fans, but so far I think they're too expensive to justify the minimal upgrade.  I'll probably re-evaluate my watercooling setup in general the next time I upgrade my CPU, but for now I have no need of a better CPU....

How did your install go?

Air

10 degrees is pretty dang impressive for air.  But how can they use the word "freezer" on air cooling I wonder?  lol

My 6750 is jealous of your 6750

How did your install go?

It was pretty easy.  Not much harder than installing the stock Intel unit but... the manufacturing quality of the clip assembly isn't as good.  A couple of the clips needed to be leaned in (leaned out at the top) to hit the holes, so I needed a flashlight to make sure they were in the holes and seated properly.  And of course, you need to remove the fan before mounting the heatsink but that's easy.

Here is the cooler I installed on mine, but it's either the case doesn't breath well or the fact that I used the heat goo that came on the cooler, but it just doesn't stay as cool as I think it should.

Arctic Silver 5 - it's your cooling friend.

Edit:  I love the shipping on this.  $5.99 for the product and $6.99 shipping.  What's pictured is exactly what you get, just the tube, maybe wrapped in plastic.  If $5.99 is actually below Newegg's cost, why not up the price and not screw me on the shipping.

It looks identical to the one I just installed:

I just ran a much longer Prime95 test with the same results but there's one thing I did notice; the fan never even reaches full speed.  It's still running several hundred RPM below max.  I might play with my speedfan settings to see just how cool this thing will run (but maybe not... I'm pretty satisfied at the moment).

BTW, you can get Arctic Silver 5 at Radio Shack for ~ $10.

Good to hear Baldegle. Let the OC begin.

My radio shack (both in town) didn't carry it.  They were more interested in selling a cell phone contract.

I just ran prime95 and ran 67-69 on each core, I let it run for 15 min.  Idle is 47-52 using Speedfan. I didn't check my fan speeds, will do it again.  I have a pair of 80's on the back of my case, only 1 has a speed sensor.

Ran test again for 15 min, fans hit 2557(cpu fan I think) and 2140 for case fan.  Running the blend test.  I guess it's OK, A/C is off today and ambient temp it @ 81 degrees with high humidity.  Idle temps are 50 on the CPU with fan running at 2265+/-10.

I'll look into this.

IIRC I've got my CPU fan set to run at 1% @ 30C and 100% @ 55C.  The max temp I've run at all day is 51C (Real Temp log).  That's through extended Prime95 tests, AH for a few hours and a movie on-line.  I haven't seen my fan hit 2100 RPM yet.  Most of the time it's in the low 1000's.

I just used the thermal grease that was applied to the FHS too but being an Arctic Cooling unit, it was probably Arctic Silver.

You might have better case cooling than me (Cooler Master).  I've got an 80mm front intake with 3 HD's behind it and a single 120mm exhaust.  There's also an intake and exhaust on the PSU, a fan on my northbridge (60mm), I've got my GPU fan set to a constant 65% (with Riva Tuner) to keep extra heat out of the case (and it exhausts out the rear... dual slot), the side panal has (had) a CPU duct (now just a vent) with another larger vent below that plus there's extra venting in the back of the case alongside the I/O panal.

I'd try using some Arctic Silver and re-seating the HSF if I were you.  That seems a bit on the hot side.

My best cooling with the stock Intel unit came when I used a plastic putty knife to make sure I had a complete, thin layer of Arctic Silver across the entire HS contact patch.  The new unit came with the thermal grease applied the same way so I just left it alone and seated it.
