Re-cooling my PC, high temps - Page 3

post #21 of 61

It says to be a push/pull fan, I'm not even sure what the cooler is, since it was never specified when I bought it. But here are the specs,

Type Liquid Cooling Fan
Fan Speed (RPM) 1500 (±15%)
Air Flow 53.30 CFM
Noise 28.44 dBA
Pressure (Max)(mm-H20) 1.50
Color Red
Feature "Push/Pull" configuration features a fan on each side of the radiator for improved airflow and cooling efficiency.

As I was browsing I was thinking about replacing the fans with these,

As for thermal paste, is it really needed?

They are gonna be OK at full rpm not sure how you care about noise.

High CFM is kind of important but mostly you want to try to find ones with good MMH20 aka static pressure. It's the ability of the fans to push against resistance in this case the fins on the radiator. These are actually pretty good at full RPM.

And yes thermal paste between the cooler and CPU is needed. It helps fill in any gaps and conduct the heat.

To be honest I don't really care about noise, since I care about cooling much more. Anyways I ordered two of those and two Bgears 140mm fans. Thanks for the help!
Will update after I install!

Blade masters are very good fans. If you don't care about noise you can get some high static pressure Deltas that push like 100+ CFM at 70DBA tongue.gif

Okay, today I just received my two 120mm Coolermaster fans. Planning on replacing my radiator fans with it, I came upon a problem. My current fans have 3 pin connectors, while the 120mm Coolermaster has 4 pins. I found an onboard 4 pin connector, but its already connected to a chip on top of the CPU block. With four 3 pin wires in my PC and only one 4 pin (can't find any other), I'm not sure what to do. Is there some sort of adapter from a 3 pin to a 4 pin? Or possibly a 4 pin to two or more 4 pin connectors on the end?

Here is the 4 pin connector on the MOBO.


Here are the four 3 pin connectors.


Here are the images of the rest of the MOBO.

The fans will just run at full speed is all.



Just make sure to index the connectors correctly.

I only see one extra fan header on that board in the bottom right hand corner. Did they not come with adaptors?

Nope, there were no adaptors. I also can't connect the 4 pins to the 3 pins since there is some sort of border around the 3 pin that prevents anything bigger than the 3 pin to not fit.

If you can take a sharp pair of cutters or a razor knife and snip the sides of those connectors out they will be fine, just make sure the notches line up.

Also does the front fan on that case work? I see what looks like the fan connector in one of those pics.

And if you can clean up those wires in front of the GPU, they are blocking most of the airflow from the front.

Well that's embarrassing, I'm having difficulties snipping off the sides. As for the front fan, it's hard to tell if it's even working when my pc is on.

I guess I can wait for the two bgear 140mm fans to come in. Since it says it comes with a 3 to 4 pin Molex adaptors.

The wires are all tied up and banded next to the harddrive slots.

I just replaced my push/pull fans with the coolermaster, and placed one of the rad fans on the top for exhaust. Weirdly the CPU temp is still around ~75C, but the GPU has substantially dropped from a usual 85C to 60C under load. I also realized that each CPU core clock is staying at its lowest clock, which is 900MHz. When gaming, this hinders performance heavily.

The CPU would be around 75-80% total usage, while the GPU is at 25-30% usage. CPU temps would be at ~75C and the GPU would be at ~60C, these are under load. However when I'm not gaming, the CPU clocks would be jumping up to 3600MHz with temps of ~68C.

Anyways I'm receiving my two 140mm fans tomorrow, which I will use for exhaust on the top. But I worry that it won't be enough to bring down the CPU temps. Might the thermal paste be the issue?
