Next time just blow on them .. very carefully.

And don't waste money on expensive TIM cleaning kits. Simple 99% pure isopropyl alcohol is the way to go.

Ok, I shall do that next time IF IT HAPPENS lol. Also, wow, I hope I didn't go a break it. !@^^%@#$^$%.
To be rather specific, I dabbed, and VERY lightly wiped. barely wiped though. Tiny movements was all when it was that.

Are they really that fragile though? I mean pins are one thing... contacts..?

*prays to the computer gods to spare my folly and allow my CPU to liiiiveee*

.... really..?

Those heat pipes are just copper tubing and bend quite easily and copper can be rebent quite often before it gets brittle. Doesn't the mounting kit come with little rubber triangles or something that you can stick onto the fan as a vibration damper?

It does come with those yeah.

So it turns out that my ram, without the heatspreader on, is still in the way of the fan if I want to mount it on the from lol. So there is a fan in the middle and the back of the cooler.

Doyll, haven't you done testing with that type of setup? It tends to be fine, yes? Anyone else feel free to chime in too.

Considering getting some 120mm fans and using 3 of those instead of 2 140mm, bu tI'm not sure how effective that will be. As it is the 140mm are rising over the top of the radiator fin stacks, so would moving down to 120mm fans be detrimental to the performance of the cooler?

The difference between push and pull is 0-2c at most. So indeed it is not a problem.

Running 3x 120mm is not as good as 2x 140mm fans or even 1x 140mm fan. The reason is stacking fans does not increase their rated airflow .. well it will because of resistance because stacking fans does increase their static pressure rating a little, but the airflow rating is the same for stacked as single.. and effectively using 2 or 3 fans is stacking them. Best way to improve performance and lower noise levels is remove grills and filters. I often remove grills, but always use filters on intake fans.

My muddled brain doesn't remember what you have for case fan setup. I would probably run 2x in front on left side and and bottom with fans. as intakes and monitor cooler / component airflow temps. Probably don't need exhaust fans. Maybe a top fin in left front position. Again, need to monitor airflow temps to components to see what is best.

 

[miklkit]

The main thing to remember is that you need to feed those beasts. That means lots of good air flow through the case. Thinking of the case as a wind tunnel with some electronic stuff in it might help. Here is what I ended up with.

These fans. They do alright, they're kinda noisy. I'm not sure the 18 decibel claim is true, but they do the trick. I'll get something new when I watercool.

I always use filters on my intake fans as well, but I have not been brave enough to break out my dremel and remove my rear fan grill.

When I get home I'll post a pic of my motherboard compartment side so you can see what it looks like. Also, I think the rear case fan and rear CPU cooler fan are interfering with each other, I'm not sure though.

Yeah I know, my setup does ok for now.

When I ran OCCT using the "all logical cores" and "avx with linpack" options enabled for a half hour, my temps went from 30-32c idle and maxed out at 56c load, ambient temperature was 21c. I know, it was only 30 minutes, but I had to go to bed. I'm going to run a 2-3 hour one tonight I think while I do homework on my laptop.

 

[maddangerous]

Ok folks, here is a 2 hour pass with OCCT. I have CPU-Z open (not that it tells much in a pic), OCCT, and CPUID HWMonitor. Let me know what you think, as I think that maybe I shouldn't have quite touched the 70c mark..



Edit: Sorry about that image, I'l break it down more when I'm done with my homework. My bad.

 

[doyll]

While the Lepa LP-BOL12P-R is not a bad fan, it is definitely not delivering 81cfm. Top rated 120mm fans like GT 1850rpm is 58cfm and EK Vardar F3 1850rpm is 63cfm.

If you want better cooling, we need to monitor the airflow going into the cooler. It's not hard or expensive. 2n'd post in "Ways to Better Cooling" show what I use.

 

[maddangerous]

No it definitely isn't moving that much air. I was actually thinking of picking up the Vardar F3's for when I get a water cooling setup. I just won't be able to for a little while yet.

Yeah I had been looking at the thermometer for a while, I've read some of the major posts in your thread.

Now, I'm not sure how much of a temperature difference there is, if any, but my rig sits up on my desk next to me instead of on the floor, but I wouldn't think the ~2.5 foot height difference would end up yielding that much of a temperature difference.

 

[doyll]

The height difference isn't a problem.
Air inside the case is always warmer than air in the room. With proper airflow it is only a few degrees even under heavy load. But if airflow is no good / system has not been check to know, the air actually going into the cooler can easily be 8-15c warmer than room.

 

[maddangerous]

How about this thermometer?

Do you think that would work ok? I can have it in 2-3 days. If not I'll head to walmart tomorrow and see what I can dig up.

 

[MicroCat]

Should do fine. It has a remote probe and the indoor/outdoor display. Only thing is it appears you have to toggle the in/out temp display. The cheapie I have, displays both at once on its low angle zero-contrast display.

Wallmart has those too: $9.94 for a fancy one

Here's one similar to mine on Amazon, but even more costly at $9.99

It will work find. I would wrap the probe in electrical tape so there is no chance of it shorting out anything. I use an all plastic clothespin and stiff insulated wire for same reason.

Have you looked on ebay? Local auto-parts house? Aquarium / terrarium shop?

Hey lookie there, it's even camo! lol

Nope, I don't use ebay. Never felt like I trusted it. Also a nope to the other two.

When I wrap it, I need to go right up to the base of the probe, correct, no further? I see some of them have a little "bulb" if you will.

Cover all the metal with tape. I would twist and/or wrap tape a stiff piece of wire about 12" long from probe back and put a non-conductive clamp (like all plastic clothespin) on it. This way you can clip it onto something and bend the wire so sensor probe is right where you want it in the airflow.

 

[maddangerous]

I'm still here, I just haven't gotten the thermometer yet.

Thanks again for the help with this everyone. Looking forward to continuing this weekend is the plan. I have to mess with my network tonight and tomorrow night, school started up again and my wireless is now crap, so I'm making cables and such

 

[maddangerous]

Ok.

I;m really sorry about the absence. I found out that I have 2 pinched nerves in my neck, and a day or two after my last post everything went downhill, so I really haven't been on much OR able to do anything. Suffered through it with the network stuff though, so there is that.

I am ready to continue if anyone would still like to help, I do have the thermometer and I'm going to get a battery for it soon (when the car gets home) so I am ready for this now. i'm going to get some details together for now.

I did try something the other day though, as I had a theory. I thought that my GPU fans were causing hot air to recirculate into my intake fan on the case, and after making a cardboard "block off plate" to cover the fan mount next to the GPU, my idle (don't recall load) temps did drop by 2c. Not much, but it was funny that it worked. I also previously took off all of my PCI slot covers, and have yet to remove the wireless card that I don't need anymore, but will do shortly.

When I do drop the temp probe in, where am I looking to put it? Pre-fan or post-fan? I would think pre-fan. That being said, am I trying to position the sensor behind the motor area of the fan, or in the path of the airflow near the blades, or does it not matter?

 

[maddangerous]

@doyll @ciarlatano @MicroCat

Suggestions on that?

sorry to do a mention.. just want to move forward so I can do a little OC

 

[MicroCat]

You rang?

Place the probe just in front of the dangerously spinning blades. Careful not to have it sucked into the powerful vortex tho. Oh, wait, you're not using a vortex fan - no worries.

Here's how ehume places his probe for cooler testing:


A little trickier inside the case. But nothing that some twist ties can't handle.

Thanks, greatly appreciated. I might have to do inside the case, I have no room on the outside of the fan, SSD's being mounted there or not. Unless it wouldn't matter if I took the front panel off..?
