Passively Cooling Nvidia's GeForce GTX 750 Ti...With An AMD Sink

Passive Cooling Works On GeForce GTX 750 Ti

For some reason, naked cards make me want to customize. If you can get motivated to enlarge this board's screw holes on your own (really, it's not a difficult task), then you're able to attach any heat sink with a hole distance of 43 mm. In essence, that's coolers compatible with AMD's Radeon HD 7700 family.

You might not think that this project is worthwhile to you, since existing partner cards run cool and quiet already. That's fair enough. But this is about cooling GM107 with no moving parts.

We can only concede that GPU Boost and its associated mechanisms are great for controlling the thermals on passively-cooled cards, even if that's not what it's meant for.

The technology works almost perfectly though, without much performance hit. It's also better about preventing the panic attacks triggered by passively-cooled Radeon cards in fanless cases. We've seen those boards crest 100 degrees, which is very dangerous.

Wrapping Up

We plan to continue tinkering, ensuring that any heat sink we experiment with has to at least be rated for 60 W and support a 43 mm screw pattern. If you're willing to follow in our footsteps, you'll end up with a nice, silent, and most important, fairly high-performance card. The GeForce GTX 750 Ti is typically a little slower than AMD's Radeon HD 7850. But that Pitcairn-based board can't be cooled passively.

  • I like the trend of returning to more techy articles. Good Job Tom's Team!

  • Excellent article; very unique take on what seems to be another future possibility for 750 Ti in the retail channel. I would have however, loved to see some thermals for the passively cooled card in a case like Fractal's Define R4 or Nanoxia's Deep Silence.

  • The temperature is alittle too high

  • Passive cooling is irrelevant these days when fans are whisper silent (mostly).

  • Can a gaming/htpc video card get any better than this? AMD, please respond.

  • i'm not comfortable with these temps, a low speed fan should be enough to lower it while still keeping the noise down

  • The temperature target of 80°C was set by Nvidia for Kepler too - all reference boards were designed to handle this w/o problems.

  • interesting, i reckon it would been a perfect match for the GTX 750, i dont know why people overlook it, its only a tad slower than GTX 750 Ti

  • False! The resistance generated the heat you had to dissipate, it was all but futile! :-D Sorry, nerd joke :-D

  • very interesting little project. i read from reviews and comments how this gpu might be suitable for passive cooling. this may be the most powerful passively cooled card i've seen so far.

  • I love passively cooled cards! I modded my old 9800GT to be passively cooled back in the day, and it was amazing! I installed an aftermarket cooler to my current GTX570, but it is not passive... still an improvement, but simply not the same.I am really hoping that there are passive options for some of the upper-mid level 800 series cards. I would love to have a more silent rig again.

  • I am a kind of person who'd not try to experiment something like this with newer models. If anything that ran hot in my college days are to be experimented I won't say no :D

  • I would like to see you test a R290X with Geforce 780Ti heatsink and compare it's performance to that of the standard AMD HSF.

  • I like the Tom's hammer logo on the heat-sink, very clever and very neat.

  • "This is for Cautious People

    If you're not willing to trust Nvidia's 80 °C temperature target (the company says 95 degrees is the GPU's thermal threshold), you can of course set a lower target of, say, 70 °C"

    So, taking the card and voiding its warranty by custom-rigging it with a heatsink that wasn't designed for it is fine, but running it at 80c? OHHHH HEELLL NAAAWWWW!!! That's just too dangerous! Won't someone think of the CHILDREN?!?!

  • the correct term, at least in Indiana, for the modification made to the screw holes is: waller. You got to waller out those holes so the new heat sink will fit.Dry

  • Well if you have 3-7 quiet fans the computer gets loud

  • Might be nice in a case that allows intake from the bottom and the side and exhausts out the top.

  • I remember putting an stock AthlonXP heasink/fan on my geForce 4200 Ti, and another stock AthlonXP heatsink (without fan) on the motherboard's nForce northbridge!
