ICOLER Jungle Leopard Prism 140mm ARGB Case Fan,Infinity Mirror Light Effect Design Cooling Fan, 140mm CPU PWM Fan 1600RPM 74.26CFM 2.13MMH20 HDB Bearing for PC Case&CPU Cooler

Nice multi-faceted light show and moved plenty of air out of the case. Appears to be of good quality fit and finish and the price is more than competitive

Looks amazing. Nice and quiet. Feels like a good quality. It's been running for 4 months so far.

I bought both the standard and reverse airflow versions of this fan for a Jonsbo TK-0 build. Given the obscure branding, I went in with very low expectations—but I’ve been mostly pleasantly surprised. The standard flow fan does make a concerning rattle when jumping sharply from 0% to 100% duty cycle. This only happens during sudden changes—like when the buggy little Radxa ARM ITX board in this machine slams the fans to full speed for no good reason. It could be a sign of a mechanical weakness that might worsen over time, or it might just be that these fans aren’t built to take that kind of abuse. Most motherboards these days have decent fan control logic that should prevent this from being an issue for most users. One standout detail: the infinity mirror design tends to highlight axial runout (wobble) on the fan hub and makes it visually distracting. I’ve seen it look pretty rough on some other brands. These, however, are impressively stable—little to no visible wobble. I didn’t break out instruments to measure airflow or static pressure, but based on experience, these move a solid amount of air—maybe even more than some similarly-specced fans from well-known brands. Noise is a mixed bag. At low to mid speeds, they’re quiet—easily masked by normal ambient noise in my workspace. At full speed, though, they get loud and have a harsh tone. Even compared to much faster-spinning fans of similar size that I own (3000RPM Noctua Industrials, 4000RPM Sanyo Denkis, etc.), these are subjectively more irritating and, in some cases, louder. I don’t buy the 29dB rating at full tilt—I'd estimate closer to 40dB. That said, in my opinion, in a well-designed build, a 120–140mm fan shouldn't need to run above ~1200RPM anyway. As long as you keep them at a reasonable speed, they're fine. Lighting is decent. The aRGB is bright enough, but not premium—there just aren’t that many LEDs. If you’ve seen something like CoolerMaster Halos, the difference is noticeable. But those also cost a lot more, and they don’t have the infinity mirror effect. So it’s a fair trade. One of the fans I received had clearly been previously installed despite being sold as new. I had to exchange it. Not great, but I don’t necessarily hold that against ICOLER Jungle Leopard—just disappointing. Final thoughts: These aren’t premium fans. They don’t match the top-tier brands in noise levels or build quality, and I wouldn’t fill a high-end case with them. But for the price, they’re surprisingly solid. If you like the infinity mirror look and don’t need whisper-quiet performance at full blast, these are a good value. Just keep your expectations realistic and you’ll likely be pretty happy.

This thing pushes so much air with so much power it's kinda insane in comparison to my older Asus fans. It's also beautiful and the infinity mirror is super cool. 100% definitely recommend. I'm using it as my rear exhaust.

Writing this review after multiple purchases of Prism 140mm ARGB AND Prism 140mm ARGB Reverse. I have 5 builds in my household where I was swapping out 120mm fan setups with 140mm fan setups in order to improve the noise quality. These 140mm Jungle Leopard look much nicer than some Thermalrights I had picked up previously. The upside is that they look great and have nice vibrant colors. Sound/volume/noise levels. When the fans spin up to full RPM these are pretty loud. BUT - They rarely need to if you have your intake/exhaust fans planned out and placed well in the case layout. Because they move so much air at a lower RPM, these fans have generally stayed at low RPM even while gaming (in all of my build setups we keep the fan layout at a positive pressure setup). So where is the 3 star rating coming from? As I said I have 5 builds in our household I have been working on and each build has somewhere between four to six 140mm fans being installed - all from Jungle Leapord. The problems that have me giving it a 3 star range but all are the same category. When installing these fans in the inverted position - regardless of whether they are normal blade or reverse blade - there seems to be a high rate of off center fan hubs which cause the fans to clatter loudly on it's frame until it gets spun up to a higher speed. The failure rate for these fans (failure rate for this review being defined as not working within expected paramaters.) Is far higher than any other fans I have purchased - practically 1 in every 4 fan I installed had these issues. Some fans with louder clattering than others. And since these fans are run primarily at a lower RPM and regularly get to a stop or lower RPM due to the setup, the clattering occurs daily and has me worried it will contribute to an early fan failure. So far the company has done well with replacements - but I have had to stretch out some of these builds over weeks in order to receive properly functioning fans. I am not sure what QC they are conducting or how they could address this issue - I consistently notice it is not noticable when the fans are floor mounted in the case - I might see a slight hub wobble but the problem for me only shows up when they are invert mounted and it shows up regularly across both normal orientation and reverse orientation fans. (I just had to send back 3 more fans last night - which is what prompted me to write this review...)

2 120 mm and 2 140mm, perfect budget fans as im slowly upgrading my pc. i also bought the connector Hub so i could control the colors color✔️ airflow is perfect✔️ noise cancellation is good but not the best✔️

Not only are these fans strikingly gorgeous, they are whisper quiet at low RPM, but sound powerful at high RPM! The LEDs and mirrors are nice and bright without being too much, and they look expensive and well made. Great budget fans with a nice weight to them. Can't recommend them enough. I will update, though, if anything happens. I only just got them after all.

This seemed like a nice fan at first. The ARGB looked great until it didn't. At first it the lights on the outer case actually synced with the rest of my ARGB, but then it stopped working. It would randomly change to different colors or just stop working at all. The only way to reset it would be by unplugging it or restarting my PC. When you want your PC to look a certain way this can really ruin the aesthetic. The ARGB on the fan blades works properly, but the outer casing does not. It's a shame because otherwise this is actually a pretty nice fan for the price, and looked great when actually working properly. I would love to try again if I was able to exchange it for a working model.

Using them with some tj prism 120mm fans they match perfectly better then paying for Lian Li fans might take a while cus import time but they are legit
