Looking for an effective way to cool my GPU.

My temps at idle are

CPU: 36
HDD: 23
GPU: 44
Motherboard: 35


My case is the Zalman Z7PLUS.

It came with a nifty removable HDD/SSD tray that had a 120mm LED fan attached to it. As a result my HDD is permanently getting cold air blow into it at almost point blank range.

I know my temps are fine, but I like having them lower. So I'm targeting my GPU for now. I'd like to lower it by about 3-5 degrees at idle.

Is this a realistic number and how can I go about doing this?

I'd like something that will last longer than my GPU. Almost like an investment.

I forgot to mention, my case has 3 x 120mm fans.

One in front, one in the side panel and one exhaust fan at the back.

The side panel can however support two 120mm fans, should I get one of those?

Hi, Are those temps from a stock cooler? Because those idle temps aren't bad, but I'd be curious to know what your temps were like under load and if you were planning on OC'ing the cpu in the future.
Most bang for your buck on air is no doubt the COOLER MASTER Hyper 212 Plus

The top Dog in air cooling would probably be the Noctua NH-D14

butt it's price it way too close to closed loop systems like the Corsair H80 and H100.

Effective way to cool your gpu? Yours didn't come with a cooling fan?

You haven't even listed your load temps, so how can you talk about cooling it, when you don't even know what the temps are?

lol

Those are CPU coolers, not GPU coolers. :hello:

What model GPU? Is your side fan blowing directly on the video card? I installed a side fan in my Antec 300 case on SLI'ed video and lowered temps by 10C on load and about 4C on idle.
Your temps aren't that bad...

It did come with a fan installed on the card, I just wanted to make it cooler.

If I install another fan on my side panel do I need to install another exhaust fan?

I was thinking of something along the lines of this

Use MSI Afterburner, adjust the fan profile. Making your profile more aggressive will bring temps down. I dropped the load temps by over 25c on my 580's in SLI just by making the fan profile more aggressive, not increasing the max fan speed, only making them faster earlier.

You aren't likely going to see much lower temps than 40c at idle on a GPU, They create a lot of heat just by nature. However 40c is still extremely cool for a gpu and nothing to even worry about. Load temps are what matter anyway. Idle temps are mostly irrelevant.

I don't really understand what you mean here by investment, nothing about PC hardware is an investment. They always plummet in value as soon as you buy them.

The fan speed was on auto @ 28%, I increased it to 100% and took auto off, so far a 2 degree drop.

Not bad :o  I'll do a load test.

Best solution

I would leave it on auto, just make the speed increase faster at lower temps. Just drag the points around on the profile curve to get them where you want them.

Leaving your fans on 100% all the time is not only noisy as hell but will also drastically decrease the working life of the fans.

You need to forget about idle temps, these temps are all extremely cool when talking about PC hardware. It is designed to run much hotter than that. What matters are your load temps. Those are what you want to ideally keep below 80c. The lower the better but you can only physically lower them so much without dumping liquid nitrogen on them lol.

It may appear to be a joke but removing a side panel and pointing a real fan (the one you use for yourself in a room) into it. works for me, had 10 degree drop xD

This does work, especially for cases that have poor cooling however it also blows a lot of dust into the case. The preferred method of course is to use a better case or add more fans to your case. Cases with filters are ideal, they keep the dust out.

That actually helps a lot thanks :)  It's on 40 atm. I know it's not an actual benchmark, but I ran Windows Experience Index and it capped at 50 degrees.

Would that effect the airflow though?

Yeah my case has removable dust filters.

It depends on the case. In a case with poor airflow where the hot air tends to stagnate a bit inside it definitely helps. In a well designed case with good airflow it actually will make it hotter just by removing the side panel. Good cases work off of strong air flow or positive or negative pressure to remove the hot air within a case. Taking the side panel off actually disrupts this in well designed cases.

You haven't even mentioned what your temps are, so I can't understand what you mean by "cooler". Seems it's pretty cold already at idle, but idle is irellevent when talking about temps.

Until you answer the question, nobody can give you an educated answer.
